Confluence: How to set Space owners programmatically (preferably with PowerShell)

[Lars Petersson]

We are setting up Confluence On-Premises and I don't really want to add space owners and set their permissions manually.

Is there a way I can do this programmatically? Preferably with PowerShell...

I found this other question: https://community.atlassian.com/t5/Answers-Developer-Questions/Confluence-set-permission-to-space-programmatically/qaq-p/507511

But the link in the answer is now a 404 :'(
