Can't find libappindicator3-1 on debian 11

["大将军王" <hackson99@qq.com>]

Hello,

i installed yesplaymusic package that was  from github on my debian 11, and i got an error: Can't find the package  libappindicator3-1.

I've checked the package from packages.debian.org, yes it is in buster, BUT, i can't find it in bullseye.

So, how can i do?

Thanks a lot!
