Not sure of your whole flow, however when zoomus:// is present it assumes that you have Zoom installed and attempts to open the Zoom app - there seems to be an issue on your device/flow and the error  unknown url scheme indicates zoomus:// is not registered on your device ---

I believe the issue is that you’re trying to open the url in a webview in the app, as opposed to the OS handling the intent/url scheme ---

You can install it from your Chromebook as any app. Then you gotta try to enter again in zoom . Hope it works for you as well ! ---
