Remove Dolphin context menu entry 'Activities'

On my plasma 5.24.6 I have this entry that seems deprecated, supposedly to create links for files and folders to an activity or other. I couldn't even find what linking a file to an activity could mean. I was expecting something like opening that file/folder into a specific activity, restricting it to that activity - but that's not it at all. (For *that* window rules are needed. ) [This](https://www.reddit.com/r/kde/comments/9xzlzm/comment/e9ybuyy/?utm_source=share&utm_medium=web2x&context=3) is the only meaningful info I could get: it should create a link on the desktop in a given activity if the option was selected somewhere... [Here](https://forum.kde.org/viewtopic.php?f=289&t=126257) there is an old discussing showing this might have been dead since Plasma 5.2. If this is true it seem like a deprecated feature, the option is absent in settings, and a google search gives nothing more. Can I remove that buggy menu entry?
