How do I remove part of the middle of my screen recording?

Hi everyone - wondering if the above concern is still valid. I've got a step by step recording across multiple slides, and in a couple of them there are some hiccups in the middle of them I'd like to trim out - start/end frame adjustment won't be the right approach.

Of course, I could re record the process, but there is a lot of real estate on the screen I'm trying to avoid highlighting.  Thanks!
