Start Rasa commandline (rasa shell) with SSL certificate

Im using RASA version 1.8.0. I’m trying to start the rasa shell using the command : python3 -m rasa_core.run -d models/current/dialogue -u models/current/nlu --endpoints endpoints.yml --port 5005 --ssl-certificate /path/ssl_certificate_file.crt --cors “*” --debug

But i’m getting the error “run.py: error: unrecognized arguments: --ssl-certificate”.

How to pass the ssl certificate argument in the above command.
