Postgres grant / revoke queries missing in diff

Recently I was removing permissions from users to update created_at:

revoke update on public.profiles from authenticated;

grant update (avatar_url, name) on public.profiles to authenticated;

revoke update on public.profiles from authenticated;

grant update (avatar_url, name) on public.profiles to authenticated;

revoke update on public.profiles from authenticated;

grant update (avatar_url, name) on public.profiles to authenticated;

revoke update on public.profiles from authenticated;

grant update (avatar_url, name) on public.profiles to authenticated;

It's working, however this queries are not shown when I use diff from supabase-js cli:

supabase db diff

supabase db diff

supabase db diff

supabase db diff

Therefore how can I save migrations ? It's a expected behavior ?
