When open, it automatically searches for network requests that contain a JWT authorization header and lists unique examples. These examples can then be selected to:

View the JSON Web Token payload.
See a list of all requests that used the same token.
Open the JWT in a new tab on https://jwt.io.
Copy the JWT to the clipboard.
