How do I change the fuction of the slider?

[Markobu98]

I have set up a couple of entities. However the fuction of the popup card is different for every light.
My led strip behind my desk for exampüle has a switch for the popup card. A desk light on the other hand has a brightness control slider.

I have tried the option "displayType" and set this to slider but it didnt change anything.

How do I change the popup so all of my lights have the slider option and not the switch.
