Have you checked out the preview of the new Graph Explorer?
You find it at https://developer.microsoft.com/en-us/graph/graph-explorer/preview

It has a better editor, cleaner UI, better history.
You have new tabs like “Auth” that shows the access token and “Snippets” that shows examples in C#, JavaScript, Java and Objective-C.

You also have a tab for Adaptive Cards.

And no more permission surprises. If you enter a query and hit tab the tab “Permissions” shows you what you already have and what you need.
