Hello there I am trying to install Digistump library to support ATTiny85 by digispark. But I am encountering a problem when trying to install Digistump AVR boards after adding an additional board URL preference as the library doesn't shows up after searching.I dont know what's the problem even after I tried from the fixes from other solutions across the web.

So, I made an alternative method to work the board by installing ATTinyCore library. But it doesn't support DIGIKEYBOARD actions. So when I try to download from library manager there is only packages for AZERTY & Belgian AZERTY layout.

So for me I need a package that support QWERTY layout. How to install the library.?
