Ion-button: text below icon

Hi, I have a simple button with icon and text.

  <ion-icon slot="start" name="star"></ion-icon>
  <small>Left Icon</small>

How can I put text below the icon?
Using ‘display: block’ is not working.
Thanks for the help

Hello something like this

<ion-tab-button  slot="start">
        <ion-icon name="star"></ion-icon>
      <ion-label>Left Icon</ion-label>

Thank you but It’s not working.

did you use ion-tab-button ? I have several of this in my application, and all the texts re right below the icons

which version that you are using? ionic 3 or 4 ?
As ion-button wrapped content with css display as FLEX.
