Options after market close

So I have been trading options for about 5 years now and ran into an issue I’ve never had before.

I had GME 22strike CC that expired Friday. At the close it was 21.76 but by 8pm it ran up to 22.16 putting my option in the money. If it crosses the strike after hours is it automatically exercised or does the buyer have to manually do it?

Either way I’m not that worried about it but didn’t really want them to get called away. Worse case I sell a CSP and keep it moving.
