[tde-users] How to stop Amarok from autostarting?

I'm running 14.0.12 on Ubuntu 20.04. Either by accident or by default, I have Amarok installed, and it autostarts on every login. I've never used it, but I might want to someday (I saw a note that it supports some streaming services), so I don't want to just uninstall it. But I don't want it wasting RAM and CPU all the time, either None of the suggestions offered by Google or ChatGPT about autostarting in Trinity match my filesystem hierarchy. How do I find the file that's causing it to autostart so I can edit/delete it? Thanks, Ran
