You're trying to apply for a closed for work permit. If you initial work permit was closed, then it makes sense. If you applied for PR recently and want to extend your wp, then you should apply for bowp. If you still want to apply for a closed work permit, yes it will ask for an explanation but you don't need to upload a separate document. Just mention the exemption code, how you still meet the eligibility of that program (whatever it is). You can keep it quite short like a paragraphHello @Miss bee,
