Ionic 4: how to decrease the height of ion-segment-button?

#1

I already tried to set the padding and the margin to 0p but still the height didn’t decrease.

ion-segment-button {
  --padding-bottom: 0px;
  --padding-top: 0px;
  --margin-bottom: 0px;
  --margin-top: 0px;
}

I cant find any properties in the documentation that I can change the value.

Also tried to change the style height without success.

#2

Anyone? please, can’t still find a way to do it.

#3 
ion-segment-button {
  height: 30px;
  min-height: 30px;
  --border-radius: 4px;
  ion-label {
    margin: 0;
  }
}
