FV Player Pro with Vimeo Pro – Convert Vimeo embed codes

Hello,

I use FV Player Pro with Vimeo Pro and now wanted to try the feature “Convert Vimeo embed codes”, but it seems it does not work for any post type.
In my case I use LearnDash and have Vimeo Videos (via the Gutenberg block) in courses, lessons and topics which are post types. If I click the convert button it will just say:
“No more posts with Vimeo embeds found!”

Could you tell me how to use this feature for just any post types? Or does someone has another idea?

Thank you!
