Signin error about twitter and unity in Firebase

Question

Already found the reason:
You currently have Essential access which includes access to Twitter API v2 endpoints only.
If you need access to this endpoint, you’ll need to apply for Elevated access via the Developer Portal

Hi I have problem about Twitter login in Unity.
I can use email google and facebook login in firebase project.
I can get each twitter account's Access Token and Secret even username via twitter unity sdk.
However when I try to login via twitter, it has One or more errors occurred problem.
I tried to use Reauthenticate but it doesn't work.
Does anyone who knows how to solve this problem? thx
