The purpose

The action fetches an access token from Google API.

It can be used to prevent your Refresh Token from being expired.

According to Google's guide, the refresh token might stop working if it has not been used for six months.

If you use it in your workflow running less often than 6 months, you can face the problem. Schedule this action to periodically access Google API and fetch access token to avoid that.

Based on typed-chrome-webstore-api package.
