Rasa X connect to mysql production db

We would like to connect rasa x (0.22.2) to our production mysql db. The mysql db is already running and collects the conversations. The endpoins.yml contains the correct tracker store for the mysql connections. We tried to used migration script but this does only seem to copy the existing conversations so that they are available to rasa x. But how can we connect rasa x to see the new conversations that are coming in - hence connect it to the mysql db?
