We are using Google ads API and we are getting the refresh_token and access_token from the oauthLibrary.

Now due to some reason (Majorly cause we are using JavaScript and there's no library for JavaScript officially from Google) we are relying on the REST API.

I want to fetch a list of Accounts attached to the the given access token. (no matter manager or not Manager) I just need the list.

I have tried the following endpoint

https://googleads.googleapis.com/v1/customers:listAccessibleCustomers

But I am getting 404 Not found in that, So I think it is discontinued, Any idea how I can fetch the list through REST_API.
