They finally got added: https://sammi.solutions/docs/commands/introduction#buttonindicatoricons

Hi Luukie13

I've been working with the devs and have sent over the necessary files in order to get this updated on the documentation.

It may take a short time for this to be updated but I think they have everything they need to update the documentation (if it's not updated already).

Thanks for suggesting this, hope you find the update useful when it's available.

Thanks
