Aurora PostgreSQL write forwarding

Does Aurora Global with PostgreSQL support “Write forwarding” from secondary clusters ?
if not how are the customers suppose to achieve this.
To put it the other way, how can they direct their application to do writes to the aurora cluster in a different region ? What should they do at networking level to make the write endpoint visible

Any guidance would be much appreciated. Thanks

FYI..

Customer has got a Primary Aurora Postgres cluster in eu-west-2

They have created a secondary read replica cluster in us-east-2

They can connect to the read only endpoint in us-east-2 from a us-east-2 ec2 instance

But cannot connect to the primary eu-west-2 cluster from us-east-2 (They are running an EC2 instance just to test the networking)
