How to automate inside a tab of an extension?

I’m trying to record my actions inside of a tab that displays a chrome extension, but it isn’t recording anything.

Example URL: chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/notification.html#confirm-transaction/3350999144376872/token-method

Screenshot of tab:

I imagine that it is because the URL doesn’t begin with HTTP or HTTPS.

Is there any workaround for this?
