Authorization header for proxied applications can clash with proxied application

I'm trying to access the apps behind authentik with an API key. This seems to work if I add an header called Authorization: Basic APIKEYHERE

The issue with this is that this breaks all authorization for apps behind it. Is it possible to use another header for example ApikeyAccess: APIKEYHERE

For example API management from Azure calls it a subscription key and it's passed in another header than the Authorization header so programs don't break
