How can Waypoint Helm expose both UI and GRPC via ALB at the same time?

Waypoint
1

hello. I want to deploy Waypoint on Kubernetes using Waypoint Helm.
Also I do TLS Termination on AWS ALB. That’s why requests coming in to ALB’s port 443 should be sent to the http port of the ui service. (Because TLS termination has already been completed in ALB)
So, I routed traffic coming in through port 443 to port 80 of UI Service using the Ingress rule.
However, there is no way to expose the GRPC Port. Since GRPC Port basically expects to receive HTTPS traffic, if you create a new ingress for GRPC and send traffic to GRPC, the following error occurs.

The plain HTTP request was sent to HTTPS port

This is because TLS termination has already been completed on the ALB.
How can I do TLS termination on AWS ALB while still exposing GRPC and UI to ALB at the same time?
