3276767 - Oauth Authentication with Bearer token does not work for inbound HTTPS connection to a Cloud Integration flow sender adapter

• Triggering a Cloud Integration flow endpoint happens with Bearer access token as authorization option. With any HTTP clients like Postman, do a call to fetch the bearer access token from SAP BTP Oauth service by performing a POST HTTPS call to https://oauthasservices-<consumer-account>.<landscape host name>/oauth2/api/v1/token?grant_type=client_credentials as steps described in official SAP Help documentation.
• In the next call triggering the integration flow's http endpoint, bearer access token is placed as Authorization Header in Postman, type 'Bearer' and token field contains the access token value. 
• All the configuration is correct, but still 403 Forbidden is received as response.
