Turn on "Less Secure Apps" on gmail account linked to domain


I am trying to turn on “Less Secure Apps” on a G Suite gmail account in order to be able to send emails using smtp

When I try to do it from Gmail it says that the settings are managed by the domain provider

How could I allow access from Less Secure Apps?

Thank you very much

This is a Cloudflare forum, and turning on ‘less secure apps’ is not related to DNS whatsoever. Doing what you describe is not something we can help with.
