google cloud platform – GCP Blockchain Node Engine API Quota Issue

I have deployed an ETH Full node using GCP’s Blockchain Node Engine. Having an issue with the APIs to access the JSON-RPC endpoint. So in the limits and quotas page they have mentioned two kinds of request limits
cloud.google.com/blockchain-node-engine/docs/quotas:

Blockchain node API per minute per project : 38400
Control plane API per minute per project : 240

I am using APIs mentioned at this URL:
cloud.google.com/blockchain-node-engine/docs/using-nodes-ethereum

And for some reason, only hitting Control Plane API quota.

My question is how do I use Blockchain node API quota?
