Getting `proto does not reside in any import path`

Version: `grpcurl v1.8.7`

I saw that issue for something like this has released already (around 3 years ago) but it appears something is wrong. Can someone confirm if I'm doing something wrong or it's not me?
I even tried dev version of grpcurl but it's same. Below is a command I'm trying to do. I'm using `Google Home proto` file for automating my Google Mini.

command used:
`grpcurl -H 'authorization: Bearer XXXXX' -import-path files -proto google/internal/home/foyer/v1.proto googlehomefoyer-pa.googleapis.com:443 google.internal.home.foyer.v1.StructuresService/GetHomeGraph`

output:
Failed to process proto source files.: google/internal/home/foyer/v1.proto does not reside in any import path
