I am getting this in postman -

{
     "code": "EAUTH",
     "response": "535-5.7.8 Username and Password not accepted. Learn more at\n535 5.7.8  
                  https://support.google.com/mail/?p=BadCredentials x7- 
                  20020aa784c7000000b005058d220b37sm21945855pfn.64 - gsmtp",
     "responseCode": 535,
     "command": "AUTH PLAIN"
}

Email And password not accepted , I have already gone through this

I recommend looking into Xoauth2 this way you can authorize the user rather than relying upon their password. I would try adapting javascript-implicit-flow to see if this will work.
