Regex HTML comments (PCRE)

Question

I am trying to get the mediaID from an HTML block however I couldn't figure out a way to skip all the other parts and only get the mediaIDs within the HTML block?

<!-- wp:pdf-viewer-block/standard {"mediaID":5943} -->

I can select the HTML comment with the followings:

<!-- .* -->

Could you please show me a way to only get the mediaIDs?
