Webhooks Basic Authorization

Occasional Visitor

Does it support basic authentication (user name + password) anyhow?
I tried to use the same HTTP cookie (as for the CSOM client - class ClientContext, HTTP Cookie: SPOIDCRL=...) to make a webhook subscription, but it returns HTTP 403 Forbidden.
Is there a possibility to do authentication in other way (using claims, username and password) without a requirement to have an app installed on Sharepoint side (as shown in the official C# demo) or creating an Azure AD application (as shown in the official JS demo)?
