I don't see the app anymore after deleting it like the phone suggested and i have a Samsung 21 Plus, I can't edit my videos anymore and i want the feature back

I deleted it just like the phone said to do and now I can't edit my videos anymore and i can't find the create movie app anymore. Anyone have any suggestions? What is the actual app name in Playstore because it's no longer on my phone I have a Samsun...
