You can launch the importer using the show function. Typically, you will want to connect this function to a button on your website.

show

The show function does exactly what it sounds like; it displays the importer. Ensure you have initialized the importer properly beforehand. Use this function like so:

const importerOptions = {
  modal: false // whether or not to show the importer in a modal
};

const importer = new FuseImporter(
  organizationApiKey, 
  importerId, 
  importerOptions
);
// ....

importer.show();
