I am trying to add a button to my HMTL form that will allow me to close the tab that is being opened in the web browser for google recaptcha v3. Not only would I like to close the tab that was opened by the program, but I would also like to terminate the program after clicking the button. Any ideas on what I am doing wrong with the following code.
I understand that I have declared 'let myWindow;', but I am not assigning anything to it. I am new to HTML, so I was wondering if I could receive some advice on how to accomplish this. Thank you.
**<button onclick="closeWin()">Close Window</button>**
**let myWindow;
function closeWin() {
myWindow.close();
}**
