Hello,
we finally want to activate our customer portal for our internal colleagues. We also have our own domain.
What settings do I need to click on here so that our colleagues without an Atlassian account can log in? I think if I activate this setting “Allow portal-only accounts to be created for new customers accessing the help center”, then people will be invited when we send them an email.
My goal is that our customers (internal) don't have to register, they should just enter their e-mail and then they can open a request.

If I enable "Use
approved domains
to grant internal customers access to the help center with Atlassian accounts", then apparently our customers get email invitations when we put our support address from Jira into BCC.
