Add elements in Mosaic widget

[CarlS]

You can also right click the date/time element and select "Inspect".

I have tried this, but nothing changes.
I can still change the date and time

#u-f1ad2fa3ea31330884f63f4bd792f777 div[data-index="10"] .datetime {
  pointer-events: none;
}

   

   

Thanks
