I can not edit the page of Contexts.
It was edited on the Contexts page until a few days ago.
Organization Membership Needed To view / edit this page, you must have an organization member with push permissions on GitHub.
It will be displayed.
I think that we have not changed authority etc.
By the way, I have the Owner authority of Github.
Even if you log in as a different Owner user, it is in the same state.
