I am experiencing a similar issue. The above mentioned YouTube video didn't address it. According to Swagger documentation, clientCredentials is a valid flow type, but when I try to edit the flow value in the custom connector Swagger Editor, I get an error:

Structural error at securityDefinitions.oauth2_auth.flow
should be equal to one of the allowed values
allowedValues: implicit, password, application, accessCode

The accessCode flow seems to be the closest option to a clientCredentials flow, but it doesn't seem to work with the API I'm working with.

Since many automations effectively serve as middleware to quickly connect two systems and possibly introduce some business logic or data transformation, incorporating the clientCredentials option seems like a valuable feature moving forward.
