Legendgrouptitle does not work with django-plotly-dash

So i’m trying to group some stuff in my scatter chart but the thing is that the title for the group does not appear. It assumes there is a group but it doesn’t display any title for that group.
I’m using dash 1.20.0 and plotly 5.6.0. I’m using an older version of dash because it’s the most recent version that is compatible with django-plotly-dash.
Is there anyone that could help me to make it work?
