InvalidSenderError: Unauthorized sender

[Zeynel]

Hello,

I am trying to send this email from the app

mail.send_mail(sender="owners_ema...@gmail.com",
to="xxx...@gmail.com",
subject="test email from app",
body="hello")

but I get the error:

InvalidSenderError: Unauthorized sender

But the email

sender="owners_ema...@gmail.com",

is the email I use to log into the app; this is the email I used to
create the app.

What am I doing wrong?

Thanks.
