How to capture if a google.script.run is being executed?

Question

I want to catch google.script.run while it is running, so I can block the user from clicking and activating the function multiple times.

Is something like this possible?

while(google.script.run.function()){
alert("Wait for the function to finish")
}

Disabling a button:

function lfunko() {
  return "Button is disabled"
}

function launchMyDialog() {
  const html = '<input type="button" id="btn" value="Click Me" onclick="myfunk();" /><div id="msg"></div><script>function myfunk(){document.getElementById("btn").disabled = true;google.script.run.withSuccessHandler((msg) => {document.getElementById("msg").innerHTML = msg;}).lfunko();}console.log("Code");</script>';
  SpreadsheetApp.getUi().showModelessDialog(HtmlService.createHtmlOutput(html),"Sample Dialog")
}
