How to set the charging speed?

I have a MG ZS EV and it charges at 50kW. Yet ABRP continually plans to charge at 150kW or more (or at least it says that is what I should do). in the particular example it says to charge for 24min at 150kW (from 37% to almost 80%) it feels like 24 min at 50kW would do that, but that isn’t what the app says to do. How do I fix it?
