How do you fix scratches and scuffs on a plastic bumper?

I went too fast pulling into my garage and ended up scraping the front bumper on my Yacht Blue EV6. There was some white paint from the garage door trim on it, but I managed to get that off. Now I’m left with scratches and scuff marks on the plastic.

Does anyone have any tips or products they’ve used to fix scratches and scuffs on plastic car parts? I’ve got rubbing compound and some wet/dry sandpaper, but I’m looking for advice on what works best to make it look good as new.

Thanks in advance!
