Changing the coolant on a 2022 MT-07.

I am trying to add coolant to my 2022 MT-07.

Does anyone here know how to change the coolant on a 2022 MT-07? Could not find a single video/post about this that is 2021+. I took the two pins out of the air vent, but it didn't seem to want to come out regardless. I don't want to end up unintentionally breaking something. Do I have to take the whole side panel off just to access the radiator cap? I was able to access the reservoir easily, but the radiator cap is hard to get to. Any help would be appreciated.
