Hello, does anyone know how the JSON Web Token works for custom connectors? I am trying to set up a payload like this:

{
    "iss": <some issuer>,
    "exp": <an expiration timestamp>
}

Airbyte will not let me add the

exp

property to the payload, claiming it's a reserved keyword. I suspect it has to do with the

token_duration

property, but I'm not sure, and I can't find anything in the documentation.
