Label of the filter, eventually example screenshot?

For my concrete use-case, I think it can't work yet, until ✨ Add Views EntityReference filter to be available for all entity reference base fields Active is solved? (Base field - see https://www.drupal.org/project/drupal/issues/3458102#comment-15818695 ✨ Add Views EntityReference filter to be available for all entity reference base fields Active )

Maybe the screenshot I suggest could just be taken from the issue summary here? ✨ Continuation Add Views EntityReference filter to be available for all entity reference fields Needs work

It doesn't actually change the label, it basically just changes which handler is used for that particular filter. So e.g. instead of numeric filter handler it opts in to the entity reference filter handler. Its actually very very tiny bit of code doing this: https://git.drupalcode.org/project/views_core_entity_reference/-/blob/1....

The rest of the module is just automated tests + helpers for updating from older versions of the patch before it got committed.
