Export frame from video as picture on iOS


I take a lot of video, but some people ask me for pictures of the stuff I Video.

Instead of going back and taking a separate photo, (or going back in time!) I’d like to be able to export a frame from a video as a photo to send on.

Every site seems to either tell me to take a screenshot, or try to sell me on an app that looks like it was made in the iOS 6 era!

Does anyone have a Shortcut or nice modern little utility they use for this? Or is it found as a feature of another app?
