Apigee Edge to X Migration Tool does not support Apigee OPDK

We have tested Apigee Edge to X Migration Tool trying to migrate our Apigee Edge OPDK into Hybrid but it failed with error:

    at file:///Users/taagare9/git/apigee/migration/devrel/tools/apigee-edge-to-x-migration-tool/src/gateway-clients/apigee-edge/ApigeeEdgeClient.js:191:13

After some investigation it showed in:
https://github.com/apigee/devrel/blob/main/tools/apigee-edge-to-x-migration-tool/src/gateway-clients/apigee-edge/ApigeeEdgeClient.js
that it trying to get token from hardcoded url of google api:

    return fetch('https://login.apigee.com/oauth/token', {
      method: 'POST',
      body: querystring.stringify({
        username: this.username,
        password: this.password,
        grant_type: 'password'
      }),
      headers: {
        'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8',
        'Accept': 'application/json;charset=utf-8',
        'Authorization': 'Basic ZWRnZWNsaTplZGdlY2xpc2VjcmV0'
      }

Could you please confirm this Apigee Edge to X Migration Tool also supports Apigee Edge for Private Cloud (On-Premise/OPDK) to migrade to Hybrid?

Start in src/gateway-clients/apigee-edge/ApigeeEdgeClient.js around the authentication request and the reported lines 191 and 209. Trace how the migration tool obtains and uses the token, then determine the expected authentication behavior for Apigee Edge OPDK. Done means the issue’s support status is established and, if supported, OPDK migration no longer fails at authentication.
