      LTI proposes the extend the initial OIDC initiation request payload with the OAuth client_id and the LTI Deployment id.

      This can dramatically simplify the tool implementation by not reverting to custom login URL per installation as a work around.

      AC:
      As per https://www.imsglobal.org/spec/lti/v1p3/#additional-login-parameters each initiation request contains:

      • client_id: client id of the tool
      • lti_deployment_id: LTI deployment id of the tool
