[SOLVED, kind of] Alternative lead image on facebook (etc)

I have a few (8) pages where the lead image is "white" (see screenshot, the background is background image on the folder view).

This is not perfect when sharing the page on sosial media.

Is there a way to set an 'alternative lead image just for facebook' on those 8 pages ?

Update: I added another image field to the content type and use that for for the folder view(s).
