Is client_id claim globally unique ?

Question asked by Neerav Mehta on Aug 30, 2019

We are investigating LTI 1.3 standard and have found that for the auth request the tool is expected to save the Issuer=>Client_Id mapping provided during the app registration process. Since the 'iss' claim for launches through Canvas have common "canvas.instructure.com". Is it safe to assume the clientId is going to be unique across all tenants (in other words is client_id suppose to be globally unique) of canvas ? Or is the client_id just unique for the particular tenant ?
