Programatic Add to "Space Shortcuts" in Confluence Cloud

I have been investigating a way to programmatically add to Space Shortcuts (see attached screenshot) as part of our space templating process. Ideally, it would this would be an available REST API to make this call but I haven’t found one that exists.

I reaching out to the community for any ideas for a work-around that would allow for Automation.

I found the below in another post, but it is for Confluence Server

“Programmatically creating a shortcut link” here:

I’ve tried Selenium but it does not play nice with Confluence.

Any other hidden gem work arounds or undocumented calls to make this programmatic?

Any help is greatly appreciated!
