Not able to delete project in GCP because of Dialogflow

[Kayo]

Hey, I'm totally new to GCP, but tried to use it for personal use cases a few years ago. Today I've wanted to clear up some things on my pc, Google etc. and saw two projects that still were open. Obv. I tried to delete them, but when I click on SHUT DOWN it just spits out an error.

It says that I've still got an open project on dialogflow linked with my GCP project. So I've tried to delete that first, but it just dosen't exist or show up. What should I do?

Hey, firstly I'm sorry for the late response, I wasn't able to access my computer for the community

Anyways. What should I select? I don't have a paid support plan and I'm first not really open to pay for a plan because of that one problem and second I can't really afford that right now.
