Azure ACI serverless push pools not working per guide

Hi, I’m going through the tutorials on setting up azure ACI for push work pools…

When trying to create a push work pool using the provided instructions…

prefect work-pool create --type azure-container-instance:push --provision-infra my-aci-pool

I receive the following error…

Unknown work pool type 'azure-container-instance:push'. Please choose from azure-container-instance, block, cloud-run, cloud-run-v2, docker, ecs, kubernetes, prefect-agent, process, 

Using Prefect cloud with local Prefect at version 2.14.12 
It's looking like the ':push' suffix isn't supported.

Can anyone advise?
