Canvas LMS LTI & Bubble API setup

Hello,

I am trying to setup my Bubble App as a LTI plugin with Canvas LMS. I am using my agency’s Canvas account and I have admin privilege.

Key Settings:

Redirect: https://paramedicine101.bubbleapps.io/version-test/lti_launch

LTI 1.3 Config:

Client_ID: 250400000000000001

When I try this URL to get an access code: '[https://canvas.instructure.com/login/oauth2/auth?client_id=250400000000000001&response_type=code&red...](https://canvas.instructure.com/login/oauth2/auth?client_id=250400000000000001&response_type=code&redirect_uri=https://paramedicine101.bubbleapps.io/version-test/lti_launch&scope=url:GET|)/api/v1/courses url:POST|/api/v1/courses url:GET|/api/v1/users/self url:GET|/api/v1/accounts/self url:GET|/api/v1/assignments&state=sample_state'

I get the correct redirect, but returned with this URL: '[https://paramedicine101.bubbleapps.io/version-test/lti_launch?error=unauthorized_client&error_descri...](https://paramedicine101.bubbleapps.io/version-test/lti_launch?error=unauthorized_client&error_description=Client+does+not+have+access+to+the+specified+Canvas+account.&state=sample_state%27)

Can someone point me in the right direction?
