Missing schema Microsoft.ApiManagement/service@2024-05-01?

I am trying to reference an existing resource using the following bicep:
```
resource apimService 'Microsoft.ApiManagement/service@2024-05-01' existing = {
  name: apimServiceName
}
```

But an error shows as:
```bash
Warning BCP081: Resource type "Microsoft.ApiManagement/service@2024-05-01" does not have types available.
```
