Using OpenStreetMap on Superset

I am trying to setup Apache-Superset, so that it uses OpenStreetMap instead of MapBox. I am currently using Superset in their local Python Version (not the Docker one), I have modified the config.py file (located in my venv libs folder), as followed:

TALISMAN_ENABLED = True

in TALISMAN_CONFIG and TALISMAN_DEV_CONFIG arrays I've added https://c.tile.openstreetmap.org in connect-src list and added:

DECKGL_BASE_MAP = [
     ['https://c.tile.openstreetmap.org/{z}/{x}/{y}.png', 'OpenStreetMap' ],
]

ENABLE_CORS = True
CORS_OPTIONS: dict[Any, Any] = {
    "origins": [
        "https://c.tile.openstreetmap.org",
    ]
}

Essentially I followed the instructions of that merged pulled request (which is supposed to have been merged (my understanding) to the version 5.0.0, but maybe it has been merged to the beta 6 which would explain the whole thing...

Since the changes have I made seem to have no effects (I can not select OSMs in the Map Style Selector), does anyone kow how to fix this?

========== Note that using the betha version resolved the issue...
