touchscreen press&hold

The layout library is powerful but it is not a solution to have a long press touch event on (bangle.js2)

Executing below code you can see that "long press" is only detected on Bangle.js1

var v_model=process.env.BOARD;
var Layout = require("Layout");
if (v_model=='BANGLEJS'||v_model=='EMSCRIPT­EN')  v_font="6x8:2";    
 else v_font="6x8";

var layout = new Layout( {
    //v vertical
      type:"v", c: [
        {type:"txt", font:v_font, label:".", id:"label", valign:-1, halign:-1 }
      ]
    },  {btns:[
    {label:"File", cb: l=>print("log: btn1"),  cbl: l=>{print("log: long press btn1"); },font:v_font, col:"#f00"},
    {label:"Launch", cb: l=>print("log: btn2"),font:v_font, col:"#f00"},
    {label:"Color", cb: l=>print("log: btn3"),font:v_font, col:"#f00"}
  ], lazy:true});

  layout.render();

Is it is the expected behaviour?
If yes, is the only alternative digitalPulse?

I am aware of @enaon using "longpress" on his eucwatch and I see that it is through digitalPulse?
