I have a checkbox that automatically sends an email to the lead once checked. I would like a dialogue box to appear when that checkbox is checked to confirm whether or not the email should be sent. If the user clicks "Yes", the email sends. If the user clicks "No", the email should not be sent but the box should remain checked.

I have read through all the Zoho documentation online and can't seem to figure out what I thought would be a simple task. Can someone show me how this can be done?

Please don't just paste a link to the very vague Zoho documentation online, this isn't helping me here.

Thank you in advance for your assistance.
