Loom isn't the only tool u can use. Go to chrome Web store, install reelia record. Here are the pros, you can record unlimited webcams, 1080P quality. No one will struggle to see in 720P. You can also trim the unnecessary parts. The only con is that it has no subtitles. If you have a string accent, you need subs so you're gonna export the video to clip champ. Generate captions for free. Then you're all done. If you have a que dm me.
