Cannot unpin apps in Debian Trixie + MATE desktop

[archisman-panigrahi]

I am running Debian Trixie, and I installed mate-dock-applet with APT.

When I right click on an app in the applet, it does not show me any option to unpin an app.

I can pin apps by dragging-and-dropping the .desktop file.

This is what I see upon right clicking:

I have the same problem under Arch, no option to pin/unip in menu

It works, but on under RMB menu, but menu when you hover over icon.
