I am currently developing a plugin for figma. As you know, you will work with two .js files and one ui.html file I am wondering if there is any way to update the ui.html when the canvas changes I know that the appropriate way to send data from the ui to the canvas is by using this in the ui.js file

parent.postMessage({ pluginMessage: { type: 'msg' } }, '*')

and using this line in the code.js file :

figma.ui.onmessage = msg =>{
  if(msg.type==="msg"){
    // ...
  }
}

so is there a way to send data in the opposite way ?
