google cloud platform – Leaked GCP API Keys – Using web service API

Google play console pre-launch report says I have leaked GCP API Keys.

I can’t restrict a google web service API to the android app. However, I did put it inside a secrets.properties file using gradle secrets plugin.

Is this enough? Is google providing a false error? Or do I need to do more?

Please help (this is my first question)

I tried using the place details android SDK version but it does not allow me to retrieve place details in a specific language whereas the web service version does and retrieving the place details in different languages is important.
