fetch is not defined in SSO Office Add-in

Tom H2o 0 Reputation points

I've followed the instructions here:

Enable SSO in an Office Add-in using nested app authentication - Office Add-ins | Microsoft Learn

Under the Call an API, TODO 4, my VS Code is telling me that 'fetch' is not defined. This is in the taskpane.js file. I've updated my Node to the latest version, V20.13.1.

This is for an Excel add-in.
