Hi, I'm adding a button to the screen and calling a restlet. 2 UI questions:
• Is it possible to add a loading icon while waiting
• Is it possible to disable the button after the click

nothing native will get you your loading bar

you can probably do it yourself using css and a little javascript

or you can using a loading bar/spinner javascript library

Ah ok, so nothing on the official docs. Just good old JS/CSS. Thanks!

while <https://sweetalert2.github.io/|sweetalert2> is more of an alert, its pretty and simple enough to work

Nice, thanks!
As the button was added in a userevent it was trivial to disable it:
```document.getElementById("custpage_btn_NAMEOFBUTTON").disabled = true;```
I also needed a refresh link in the button, just added a N/ui/message for it:
```var mymsg = message.create({
      title: "My title",
      message: dataFromRest.body + "&lt;p&gt;&lt;b&gt;&lt;a href='#' onclick='window.location.reload(true);'&gt;Please refresh!&lt;/a&gt;&lt;/b&gt;&lt;/p&gt;",
      type: message.Type.INFORMATION
    });```
I'll try the spinner later on! Thanks
