gh pr create --reviewer ... is slow in repos with many possible reviewers #11501
Description
CLI Feedback
I run gh pr create as part of a GitHub Action, after doing a git push before.
It's unexpectedly slow, takes over one minute.
I'm wondering why it's so slow and how I can debug it further and improve it.
Here's the command I run:
gh pr create --draft --reviewer jakub-g --title 'title' --body 'body' --base jakub/test1 --head jakub/test2
(the diff between the branches is a single commit)
When I run with GH_DEBUG=1 I can see a lot of GQL requests, that overall take ~1 minute, but it doesn't help understanding what are those requests:

Question
What can I do to debug this further?
