<lwc-button/> - launches the LWC Modal on click
- Optional Arguments:
  - icon-only - display the button as an icon without "Connect wallet"
  - disabled - mark the button as disabled. NOTE: in react disabled={false} will not work - attribute must be omitted
<lwc-modal/> - render the modal on its own
- Optional Arguments:
  - on-close - callback when modal is closed
<lwc-connector-list/> - render the list of connectors on their own
more components coming soon

Lightning wallet connect exposes the following events:

lwc:connected window event which fires when a wallet is connected and window.webln is ready to use
lwc:modalclosed window event which fires when Lightning Wallet Connect modal is closed

    <script>
      window.addEventListener('lwc:connected', async () => {
        // TODO: hide the lwc-button
        const invoice = // (...invoice generated by backend)

  return () => {
    window.removeEventListener('lwc:connected', onConnected);
