How do I add multiple SP permission groups to an item in one HTTP request?

[cardinalpipkin]

I can successfully add permission groups to a newly created item. But I'm wondering if it's safer and quicker to be able to add multiple permission groups to a newly created item in one HTTP call.

Here's the flow:

As you can see I'm giving the item 2 different permission groups and I need to give it a 3rd, but I think there may be a better way using just one POST HTTP request?

The way the HTTP calls are built you can only do one permission group per POST.  That's not a limitation in Power Automate, its a limitation to the way the permission groups work.  Even if modifying them on-premises using C# you can only process one group at a time.
