### Problem Description

Auto-generated playlists organized as albums normally do not appear in the search, nor are visible when the user opens the playlist section under the "artistname-topic" channels.
This issue was addressed by Newpipe and Piped with their search filters. I'd like to see a similar feature implemented here.

### Proposed Solution

Since these playlist can be normally accessed via their url's (on YouTube, FreeTube, and basically any other front end), they can be indexed/organized based on the data within YouTube Music.

### Alternatives Considered

If there is a difficulty in indexing the playlists from Youtube Music, FreeTube can attempt to collect url's based on their internal information (e.g. id,author,title) and automatically turn them into temporary playlists that would be seen in the search.

### Issue Labels

ease of use improvement

### Additional Information

I am not a developer, so my solution suggestions are speculative.
I've chosen this specific repository because it's has a relatively large community support, consequently, the greater the chances that my request will be considered.
Additionally, here is a screenshot of a Piped Instance using such kind of filter.

No files, tests, or entry points are named. First trace how search results and artist-topic playlist sections are sourced, then determine how YouTube Music auto-generated album playlists could be indexed or exposed; done means those playlists can be found through a dedicated search filter.
