Hello, how do you remove the global button? Yes, you can, or do you have to remove the entire cover?
No need to remove the cover, that’s a bad move. The ‘cap’ slips on top of the button
If you have sticky tape on the end of pliers you can lift it off (with care) - or maybe with two thin guitar plectrums to prise it up
see other posts and links on this ‘method’ … do your own due diligence and proceed patiently., it is rather easy, i have done it many times
