I read an article about how to authenticate angular app with firebase API using Auth0.

I followed the step described in here, however I would not be able to call the Delegation endpoint from Auth0 to get a token for Firebase API using curl command.

How do I do below:

curl --data \
"client_id=YOUR_CLIENT_ID&\
 &grant_type=urn:ietf:params:oauth:grant-type:jwt-bearer\
 &refresh_token=\
 &scope=open_id\
 &api_type=firebase"\
 https://YOUR_ACCOUNT.auth0.com/delegation
