When creating a custom connector for a group of API calls using a bearer token to authorize (not through OAuth2), it is not allowed to use the "Authorization" header in the Request section, this shows an error and won't allow you to save the connector. It seems it has to go via the Security section -> API Key. Though, this API Key is set when the connector is created within the logic app, while a bearer token only has a short lifespan (hours). Hence, it would be useful to be able to pass the bearer token as part of the request (header) during each run. This way, the bearer token can be fetched in a first step and then passed on to the custom connector, having a fresh bearer token every time.
Is it possible to achieve this in some way currently, using custom connectors of course and not the standard Web Request connector?
