homegraph api help !!!

[mio1]

I used a translator. Please understand.

I'm trying to register iot on google home through google action but there's something wrong with the authentication.

The current situation is that I try to use the homegraph scope after receiving the authentication token with Google login oauth, but I am blocked from accessing it: Approval error message appears

I've checked all permissions, client id, secret key, etc. to resolve, but I don't know the cause. Please help
