Go to the "My Question Pool" → "My Questions" section, select the question(s) you want to share, and select "Share" → "Share in Group" via the link and select the group you want. You then have the option to decide whether the question in the shared pool may also be edited or not. Translated with www.DeepL.com/Translator (free version)
Attention the shared questions are only referenced and not copied. Subsequent changes are made to the same question by all authorized persons. If you want to keep the original question, you should copy it first.
The use of the review process as well as the use of the status also lends itself to the joint work on questions.
