How do I delete?? – Custom bubble - color & font Review

I can’t find the app in my settings nor can I delete it! And I’m looking at all the reviews because some know how to delete it and I’m still confused on how. This app only let me type one thing before it tried to make me pay for a upgrade but I’m having money issues and need to save to pay rent and taxes so If the apps gonna make me pay then I’d rather delete the app but I don’t know how. And I’m confused I’m a slow learner and really need to know a step by step delete please I’m begging ?.
