Unfortunately it doesn’t work in **InDesign** 🥲  
I opted to use the (UXP) Dialog, even if they are not fully compatible.

I recommend using the helper library “_Adobe XD Plugin Helpers_”.  
In my case I was using InDesign 19.4 which has a bug that always places the Dialog in the lower left corner ignoring also the dimension provided.

I randomly found a solution: force the dialog dimension via css for some reason make InDesign display the Dialog in the center of the screen.

```auto
dialog {
  width: 600px !important;
  form {
    width: 100% !important;
  }
  max-height: 100px;
}

```
