I just bought an AC. Will I save more money by having it turn on and off periodically throughout the day, or by letting it stay on all the time? (relevant pics inside)

I know this question has been asked before, but:

1. From what I can tell, air conditioners become more and efficient every single year, and the model I bought is quite new, says 2021 on its labels (I've attached pictures of these below).
2. I live in India, so I'd assume that that factors into the discussion. Different weather, a 240v electricity supply, and so on. The humidity is 77% where I stay! There are probably other things too that I'm not even aware I need to consider.
3. It takes about a half hour after the AC is switched off, for the temps to start rising in my room to uncomfortable/suffocating levels, especially around noon.
4. Mine is apparently a "triple inverter" AC? The specs say: "Compared with conventional inverter technology, Haier Triple Inverter Plus integrates TLFM inverter control, PID inverter control and A-PAM inverter control to achieve smart control of the air conditioner and, in the meanwhile, maximize comfort, reliability and highly efficient performance." I'd assume that that matters.
5. This is a single 1.5 ton split-AC unit, for just a single room, not central.

Is this enough for smarter people than me to do the necessary calculations?

ISEER = Indian Seasonal Energy Efficiency Ratio

"ISEER is an evolved rating methodology for air conditioners that factors in variance in higher temperature in India and rates air conditioners accordingly.  ISEER measures energy efficiency of air conditioners based on a weighted average of the performance at outside temperatures between 24 and 43 degree C based on Indian weather data." | "Generally, the outdoor temperature is set to 35°C and the indoor temperature will be set to 27°C with a 50% humidity value for calculation purposes." - from the internet.

Ever since I started working at 17, having my own air-conditioner has been a dream of mine, but I kept putting it off because I knew the power bill would be too high. I feel like I was forced to buy one today because summer's starting to kick in real hard this year, and like most everyone else I'm working from home now; the rising temps/humidity were actually severely affecting my productivity, so much so that I was actually losing money because I couldn't adhere to my time-commitments because I was too hot and bothered all the time!

As happy as I am to finally have achieved my dream (yes, yes, eye-roll indeed) of being able to afford my own AC, I'm legit scared about the electricity bill this month. I tried buying the most energy-efficient unit I could afford within my budget, but still.

Help, please? I only "need" the AC from around 9am to 6-7pm, that's when the temps are most... disgusting. And I have this "smart" IR-blaster a friend gave me that you can program routines into. And I don't really need the temp to go below 25-26 degrees Celsius.

Given all the above, will I save more money by having the smart-remote turn the AC on and off periodically throughout that window-of-time, or by having the AC stay on the whole the time? If the former, what would be the best sequence? One hour on, half hour off? Two on, half off? (remember, a break beyond 30minutes and my room's back to being sweltering)
