Is it possible to add Questionnaires after the requisition has been created and published?

Summary:

I'm trying to add an additional questionnaire to the candidates in this requisition, but when I try, I don't see a button to add the already created questionnaire.

Is it only possible to add these questions while the requisition is being created?

Is any extra configuration or role required to perform this action?

Content (please ensure you mask any confidential information):

I followed the documentation to be able to add the questions in the "Questionnaires" section but I still can't display the questions.

Does the questionnaire have to be in the Recruiting >> Prescreening folder?
