Signing request with only API key

[simoroma]

As far as I understood, using a Client ID and a secret is a legacy way to call APIs: https://developers.google.com/maps/premium/authentication/client-id/url-authorization

I would like to call the API and adding a signature using only my API key. For example doing the following:
client = googlemaps.Client(key="<MY-KEY>", client_secret="<MY-SECRET>").

Nonetheless, no signature is added if I don't add a Client ID (which I do not have).

I managed to do call the API with a key and a signature adding this:

        # Add signature
        if self.key and self.client_secret:
            params.append(("key", self.key))
            path = path + "?" + urlencode_params(params)
            print("Add signature to Google Maps API call.")
            sig = sign_hmac(self.client_secret, path)
            return path + "&signature=" + sig
