I was designing a plugin, where one could click on a selected object and show all its properties onto the same figure. I want to dynamically change selection once user clicks any other shape but i have problem figuring out why my Figma.on not working.

Here is the code:

function runplugin() {

  let selectedElements = figma.currentPage.selection;



  if (selectedElements.length === 0) {

    figma.closePlugin('No elements selected');

    return;

  }



  if (selectedElements.length > 1) {

    figma.closePlugin('Please select one element');

    return;

  }



 console.log('hello');

}



figma.on('selectionchange', () => {

  console.log(figma.currentPage.selection);

  console.log('j');

});







figma.closePlugin()

Code is changed to debug. Please Help
