I have some unused bottles of G64 that I bought brand new, was going to do a coolant flush but decided not to last minute as it was only a 3 year car at the time and very low miles.
If you are interested you can have them for a good price.

Cheers mate, not sure if it's G64 I need, what colour is it?

Ah right, cheers for the offer but I think I'll just let the warranty deal with it

As it turns out none of my findings were correct - it's HT-12 I needed. Seemingly G64 is also usable but I can't find any confirmation that it is exactly the same

The dealer parts department sold it to me, to be honest I'm not 100% sure of the colour that was in it as the expansion tank is very difficult to see into, it could easily have been green.

HT-12 is the standard coolant for all more modern BMWs, for a 2021 it's almost certainly what it came out of the factory with. It will be the same for an S but I don't know if a 2019 will use the older stuff. Contact your local dealer parts department and give them your reg
