Nextcloud does not recognize Pico themes other than the default.

Not quite sure which āthemesā folder I should be using. The NC admin panel (settings) says to put the theme in the last folder shown above, but the theme does not show-up in the drop-down list.
I also changed the owner of all theme files to āappuserā to match that of my NC install, to no effect.
Using Nextcloud 27.0.1 (under Docker)
Pico 2.1.4
Files in the theme folder are:
dr-sr-sr-x 5 appuser users 4096 Aug 6 08:10 .
drwxr-sr-x 3 appuser users 4096 Aug 5 22:12 ..
drwxr-sr-x 2 appuser users 4096 Aug 5 22:12 css
drwxr-sr-x 2 appuser users 4096 Aug 5 22:12 img
-rw-r--r-- 1 appuser users 5178 Aug 5 22:12 index.twig
drwxr-sr-x 2 appuser users 4096 Aug 5 22:12 js
-rwxr-xr-x 1 appuser users 976 Aug 6 08:10 pico-theme.yml
-rw-r--r-- 1 appuser users 5702 Aug 5 22:12 post.twig
I manually added to pico-theme.yml file as it was missing, but again, no change.
