Trigger an action when a different folder/playlist is chosen in Music

I'm working on a very large list of songs in Music, involving many playlists/folders/etc'.
All the time I am switching between them and searching for songs.
In the latest Music app (MBP, not mobile) I need to manually invoke the search/filter field by pressing Cmd+F every single time I switch playlists/etc. (As soon as I switch again, its again "gone").

Can anyone suggest a "simple/I can understand" (based on pure KM, no scripts or so) to automate the search field invoking?
Thanks in advance.
