How to add Logo and button on the dashboard toolbar

Sorry to sound a bit harsh but this is a common request and has been answered many times.

Did you do any research ?

I just tried searching the forum for "button dashboard toolbar" and found 50+ results!

You could also try "button on head" or "button on topbar"

Hint: you could also look at my post from 2 years ago about this topic :wink:
