xfce4-mailwatch-plugin v1.3.0 (Gmail Account)

Hi, since Google disabled this option: https://myaccount.google.com/lesssecureapps

xfce4-mailwatch-plugin is unable to receive any email from my account. I'm getting below error:

[Gmail] Received HTTP response code 401. The most likely reason for this is that your GMail username or password is incorrect.

But I can check my emails through, when click on the icon.
