Wordpress and Instagram integration with pre-moderation?

Question

Instagram

It is necessary to place a photo from a group on Instagram on a site running wordpress.
The bottom line: when a user enters the admin panel, he sees a group feed with posts from different people, he puts those photos that he likes into the appropriate album and all this is displayed on the site in the form of galleries.
I used Google, basically everything I found is paid.
There is little experience with wordpress, tell me which plugin is most suitable in terms of functionality?
Preferably free of course.
