is there a way to delete ONLY retweets?

[skythehooman]

I don't know anything so i don't understand if there's an option to only have the script delete just retweets?
i have an art account that's been clogged up by a bunch of rts i did years ago and i'd like to delete just those if possible.
otherwise if it's not possible, is excluding replies from getting deleted a thing? because i could just filter out my media posts one by one but not my replies
i already did download my archive if that helps

Retweets all have a similar format, they start with the text RT . I have not tested this, but I am assuming with "unretweet":true and "match_any_keywords":["RT "], theoretically it should only delete retweets.
