Write Characteristic to Web Bluetooth.

I have a pixl that currently advertises a custom service and characteristic which a puck can then discover connect to and write to.
I would like to replicate this with webbluetooth so that the puck can control a browser app instead of the pixl, is that possible? obviously doing something on the page instead of turning on the LED
Below is the code on my pixl.

NRF.setServices({
  "60970001-dddd-49b8-acea-2b7f5d2660dd": {
    "60970002-dddd-49b8-acea-2b7f5d2660dd": {
      value : [0],
      maxLen : 1,
      writable : true,
      onWrite : function(evt) {
        digitalWrite(LED, evt.data[0]);
        digitalWrite(D13, evt.data[0]);
        
      }
    }
  }
}, { uart : true });


// On disconnect
NRF.on('disconnect', function() {
  digitalWrite(LED,0);
  digitalWrite(D13,0)
});
// Change name 
NRF.setAdvertising({}, {name:"BLEPTT"});6
