I am a developer who has been tasked with implementing GraphQL for some SPA apps. Initially I created an endpoint then when the endpoint UI is loaded, the page is blank and the ability to create other endpoints or edit the one I just created is gone. What do I need to do so that I can create other endpoints or edit the one I have created? I can use CRX/DE to delete the endpoint I just created and the "Create" button is again visible and I can create a new endpoint but after the page returns to the GraphQL UI, the page is blank and the button is no longer visible.
