OIDC not working in Appsync

I am using OIDC authmode to connect to my AppSync and I am trying to connect using this code:

` const todoData = await API.graphql({
query: listRooms,
variables: {},
authMode: 'OPENID_CONNECT',
authToken: 'MyToken',
});`

But I am getting the following error=> Error: No current user

The token that I am suing works fine testing from the appsync query console.

Start with the API.graphql call shown in the issue and compare its OPENID_CONNECT authMode and authToken handling with the same token in the AppSync query console. Reproduce the No current user error, then identify the missing configuration or request detail and verify that the listRooms query succeeds through the client.
