When Google launched featured snippets anchor and highlight feature, it came with added tracking parameters to the URL you click on from Google. Google adds on #:~:text= to the URL you click on from Google.
This is what it looks like:
Glenn Gabe asked Google if they will add this as a filter to Google Search Console. Google basically said, unlikely. John Mueller from Google said "My feeling is showing those in SC would add a lot of clutter, since the snippet, and with that also the linked fragment, can vary from query to query, even for the same URL."

Here is a bit more:
I'd see us showing those fragments as a bug, it's not consistent with the general focus on canonical URLs. I'd prefer we unify everything to canonical URLs rather than add more variations (but I suspect you'd like more variations :-))

Note; back in 2016, Google tested a featured snippet filter in Search Console. But then a year later, Google removed that test. Although, hope should not be lost, Danny Sullivan from Google said it might happen one day.
