I am unable to access Web Serial API in Chrome in a MacBook Air with M1 processor.

Expected Outcome: 'navigator.serial' should be accessible in Chrome browser.

Actual Outcome: 'navigator.serial' is undefined and hence I am unable to access Web Serial API.

Chrome browser version: Version 91.0.4472.114 (Official Build) (ARM)

Hardware device: MacBook Air with M1 processor (ARM)

This is a Chromium issue, not a specification issue. Please file a report on crbug.com with a link to an example site demonstrating the issue you are encountering. The most common reason why navigator.serial will be undefined is because this API is only exposed in secure contexts, which means the page was served with HTTPS or from localhost.

To test whether the API is exposed properly on your system try clicking the "Serial" button on https://permission.site. It should show the device permission prompt.
