Supabase Security Advisor says "Function Search Path Mutable"

[XStarlink]

Bug report

Describe the bug

Hello,

First of all, thank you very much for this great script that helps me manage the admin part of my App!

I recently noticed that the new Supabase Security Advisor raises a warning on the functions provided by your script, I don't clearly understand what needs to be changed to make the warning go away but I wanted to warn you.

The warnings says:

Issue: Function public.delete_claim has a role mutable search_path
Description: Detects functions where the search_path parameter is not set to an empty string.

Thanks in advance!

To Reproduce

Steps to reproduce the behavior:

1. Install supabase-custom-claims in a Supabase project
2. Go to Advisors on the Sidebar
3. See warnings
