I am working on a Power Automate where I create a new project site, apply a site design and customize permissions. I have managed to get the first 2 working, but I am having trouble with the custom permissions.
I need to create a new permission level (to allow users to manage permissions) and apply it to a group of users. I can create the SharePoint group using Power Automate, and apply an existing permission level as well. However, I cannot see a way to create a custom permission level.
I also checked in the site design JSON schema and I didnt see anything about permissions here. Has anyone created a custom permission level using Power Automate, or Site Design?
