Can't edit permission JSON on AWS, despite it telling me I can

Question

I am hoping to set a time limit on AWS permissions for my users.

But I cannot edit the policy JSON file, despite it saying I can:

Note the line You can still view or edit the JSON policy document.

But then it says read-only. Is there a way to download the JSON, edit it, then upload it?

Or is there another way to put a time limit on user permissions?

Answer 1

Looks that you are trying to modify "AWS managed" policy (you can see the small aws logo before the policy name) and that is not possible. You can create a new policy (will get a tag "customer-managed") and then you can copy/modify permissions
