@burnout426 thanks... I thought so.
Well the best should be an already setup option like ot has to Whatsapp, Telegram, etc... that way it should work without need workarounds but I think they will not do that.
I tried extensions but these only works in icon on title bar and I wanted something on sidepanel.
And I wanted to put the things I use together in the sidebar but seems impossible 😃 right now the Whatsapp is in the top part and the Outlook in the botton lol
