Can starter accounts to collaborate with a professional account?

My org has a few professional accounts, but we would like to collaborate with a few stakeholders on very basic editing → change the text to see if it fits in the design. Can they simply have a starter account to do this kind of collaboration? We don’t need to share the Team Library with them.

What happened in the past is that we shared the design files with the stakeholders and gave them ‘edit’ access. Then, Figma automatically converted into pro licensed users.

Would keeping the Figma file as a ‘draft’ and then invite the collaborators with ‘edit’ permission prevent this issue?
