API and octokit method to change PR status to draft

Hi

Is there any method to change the status of a PR back to draft with octokit? I cant see anything in the API definition neither in octokit (i assume both are mirrored)

https://docs.github.com/en/rest/reference/pulls
https://octokit.github.io/rest.js/v18#pulls

Looking at the inspector, i can see the endpoint called is pull/{PR_Number}/convert_to_draft

But this is not in the official documentation

Any idea on how this can be done with octokit?

Thanks
