Why am I seeing Bad Client ID?
If you're trying to verify your Google sheet and you're seeing an error:
Bad Client ID
What this means is that you're not on Google chrome browser. Maybe you installed the extension on brave browser or opera.
As of today (June 2021), Group Leads would only work on Google Chrome browser.
To resolve this, just make you are using the extension on Google chrome or Firefox.
