Hi, Thanks to reaching to us.
The consumers can request a connection to a private-link service by using either the resource URI or the alias. To connect by using the alias, create a private endpoint by using the manual connection approval method. To use the manual connection approval method, set the manual request parameter to True during the private-endpoint create flow.
This manual request can be auto approved if the consumer's subscription is allow-listed on the provider side.
To learn more go to controlling service access.
