Use MediaFinder to add media in paragraphs to groups

@msnassar I think, we have misunderstanding.
We have media finders plugins, which get us entities, where we can find medias, but also we need to know to which group we can assign these entities.
So, we have this hook groupmedia_entity_group, which allows to expose more groups to which we want attach medias.

BTW, I think it is a good idea to have also group finder plugin. we can work on this later

Your plugin still can be useful to handle this case 📌 Handle paragraphs, when we add existing entity to a group Closed: duplicate .
Let me check one more time a bit later. I am still busy with another task currently

@LOBsTerr
I have already built group finder plugin for a website. I am planning to contribute it very soon...
It helps us to solve many cases. e.g.:
- Attach media to a group (that has a media field) when creating new group.
- Attach media using media library.
- Find group in pages other than the group page itself.
- ....

@msnassar, yes, please, do it, but could you create a separate issue for it. It would much easier to review for me. Thanks

@msnassar Thank you for your contribution
I have checked your plugin it works as expected.
After double checking we don't need group finder hook, because we get necessary group ids from the entity to which the paragraph is attached. Plus it will be handled during the update!
