GRPC Call from APIM inbound rules

Question

Hi, i have an existing http API in Azure API Management and it works fine. In the inbound policies of that API i have some requests to other APIs using the send-request policy, but now i need to add a new policy to call a GRPC service but i think send-request policy is not supporting grpc calls. Is there any way to add a policy to call a GRPC service? Thanks for help.
