Can i assign a Guest to a Space via API?

[Juergen Koeck]

I use Confluence Cloud and i want to assign a Space to a Guest, is this possible via REST API and if so, how?

@Juergen Koeck you can use Add user to group endpoint to add users to guest group.

Yes, but this is not what i want, i want to Assign a Guest to the Space. Confluence Guest or do guest users still get Access to a Space with the new guest feature by adding them to the group?
