I'm trying to add an option to the "Right Click Menu" app

I’m trying to add a custom option to the “Right Click Menu” app on Nextcloud and I’m having some trouble.
Below is a link to a YouTube video of what I’m trying to do:

Let me know if you can help me or steer me in the right direction to accomplish this option.

I didn’t open the video, but there is a files_rightclick app. However if you’re targeting>=NC28 Files migrated to Vue so I don’t know the status of that app. You may want to check out the repository on GitHub for it and/or search for issues that reference it in the server repository.
