You can add the names and photos of team members on the cover or homepage of PPT to show the identity and participation of team members.

1. Add the names or numbers of team members in the bottom or sidebar of each PPT page, and indicate which member made or edited the page.

2. Add the signatures of team members on the last page of PPT, which can be arranged in alphabetical order or according to the specific contribution of each member to commend the work and contribution of each member.

3. If you can't add photos of team members or the signature typesetting is not beautiful enough, you can also add a list of team members and specific contributions in the appendix of PPT for others to check and refer to.
