Pull Request approval by Jenkins

My use case is : When “pull request” is triggered in gitea, Jenkins shall validate the PR and if the PR validation by Jenkins is not pass, the code in gitea shall not be merged to our main branch. how to set gitea to make sure the case above?

I have installed gitea v1.23.7 and Jenkins v2.508, i do configured the “branch” in gitea repo setting as the below menu:
“Protection branch ->Pull request approved(合并请求批准)”

but i do not know what`s shall be put in “Status Check ” under “Pull request approved” to achive my use case. is there any sample for the pull request approval settings ?
