Typically, a 535-5.7.8 error indicates that you did not enable Less Secure Apps on the inbox side of your email address. If you see this error, navigate to this link below and double-check that this setting is enabled, and try connecting again.

If this setting is enabled under the inbox and you are still experiencing this same issue, double-check you are utilizing the correct login information for this Google inbox.

You might also need to add the inbox using the SMTP/IMAP option instead of the Google Workspace integration.
