Error disable SASL authentication to send emails from gmail

SYSTEM INFORMATION
OS type and version Almalinux 9.7
Webmin version 2.621

Hello everyone, I want to send emails from Gmail, configuring the “Send as” option, it asks me for SMTP access to my domain email account, but it responds with the error “535 5.7.8 Error: authentication failed: authentication failure”, I already think I disabled SASL authentication, I hope for your help.

I attach images of the error when trying to configure, as well as the postfix error log and the configuration.
