piCorePlayer +Allo Boss2 OLED

Hi PiCore Team,

I'm not having much luck setting up my Allo Boss2 OLED with pCP.

Under Squeelite settings > ALSA Mixer > Parameters and notes for your DAC it suggests I "Load Extension allo-boss2.tcz for OLED screen". When I check all of the extension repositories I'm not seeing this. Is this instruction no longer relevant?

I did just find some instructions on your GitHub, should these be the ones I follow? https://github.com/piCorePlayer/allo_boss2_oled_p3

Thanks in advance,
Alex
