Gsuite - App blocked

I am trying to compose mail using gsuite
But when i run bot, gsuite access is blocked.
I have disabled the 2 step authentication and less secure app as On

How to resolve this?

Make sure the services account is setup so that external application can access it

As it is enterprise application it’ll be managed by admins. They can alter the settings. below link shows the steps to whitelist

Did you have a look at the above mentioned link?

That settings should be enabled and for verification is recommended to have Chrome as the default browser.

Yeah, i have read the document. Please find the below screenshot and guide me.
