Issue with using route API

[EdwardGrasshopper]

Description

I got this error when I tried making a route from an origin to a destination.
MapsRequestError: DIRECTIONS_ROUTE: REQUEST_DENIED: There was an issue performing a Directions request.

I just started to use my Google Maps API and did notice the issue located at this (https://issuetracker.google.com/issues/255359343), and I currently have my API key set to unrestricted, but I'm curious if this behavior is expected while the issue is pending?

I also got these errors too:
Uncaught (in promise) MapsRequestError: DIRECTIONS_ROUTE: REQUEST_DENIED: The webpage is not allowed to use the directions service.

and

Directions Service: This API project is not authorized to use this API. For more information on authentication and Google Maps JavaScript API services please see: https://developers.google.com/maps/documentation/javascript/get-api-key

I can provide more info if necessary.

Steps to Reproduce

Use the useMap hook and the useMapsLibrary hook using
const map = useMap();
const routesLibrary = useMapsLibrary("routes");

I followed all the general steps used in this video put out by Google Maps:

What is currently happening is that the Google Maps team is in the process of moving the Directions- and DistanceMatrix APIs into the 'legacy' state. This means that usage in new projects is discouraged (officially no longer possible, but there seems to be a way, see below), but they continue to be supported as-is for existing projects: https://developers.google.com/maps/legacy

The main takeaway here is this: While there already is the library named "routes", it doesn't use the new Routes API, but rather the Directions API, which is now in legacy. There currently is no client library for using the routes API in the browser.

So if you want to use the Routes API instead of the Directions API (and there are good reasons to), you can either call the routes API on the server and use the @googlemaps/routing package, or you have to call it via fetch on the client.

If not, you should still be able to enable the legacy directions API by using this direct link: https://console.cloud.google.com/apis/library/directions-backend.googleapis.com (however, that might just be a transitional thing that could stop working at any time).
