Applications Launcher in Gnome Dock and Workspace Overviews

I have switched from Gnome to Gnome Classic (on the logins screen bottom right corner gear icon gives options: Gnome, Gnome Classic, and Gnome on X11) because I cannot use screensharing features on some apps like Teams, Slack etc. I have managed successfully get Gnome Classic work and it fixed my screensharing issues with those apps, but not Gnome on x11, gonna try again.

What I miss now is the applicaitons launcher icon that opens the Overlay shows Applications and the Workspaces on that same overlay, and the functionality Workspaces Overview itself alone (I guess I was opening latter one with from keyboard Super or 3 fingers swipe up)

How to bring them back?
