With a personal access token I could submit a Github issue having stored the token in the authorization header but not with a client/application token. The two token types differ in the length and use of the capital letters:

personal token: ghp_4SnSMyxWKzkxktEQMV4fZu1iUfyGm3qAP2a3

client token: 5mpuw6q1g7uen5p2ane3gcp89ivm1dygrcjj

Tried prepending the client token with ghp_, didn't work. How do I get to submit an issue with a client token?
