Hello and thank you for the PR. I added a commit to check that there is a queue to which the user can enqueue items. I also made the enqueue option available when sharing playlists to NewPipe. I also moved the option up so enqueue is positioned right after the other player options.

~~The commit history of your branch is a little strange.~~

~~I wanted to do a quick rebase but that's not possible without resolving a bunch of conflicts. Please cherry pick the two commits, fix the conflicts, undo the changes in libs.version.toml and force push. After that this is good to go.~~

Somehow I missed this comment. My bad.

Actually in my testing I have seen one bug. Start playing an item in the app -> click on external link, select enquque option in the menu -> open the app, very that external item is now added -> within the app long press on another item and try "enqueue" and "enqueue next" option. The "enque next" option did not add item to the list at all.

I see there have been a PR with "enqueue next" as well, so will test this workflow in 28.1 apk

Update: Tested on v28.1, not seeing the issue
