How to configure leave request notification?

Hi, I am trying to create a notification to notify that leave request has been approved. I am wondering whether my setup is enough.

I left Sender empty, because I didn’t create any email account yet.

Is my condition okay?

What is set property after alert?

For Recipients, I have set Send To All Assignees.

I left the message part empty

@anilpoda condition looks fine . after alert is a value that changes after the notification was sent , you dont need it in leave application .
send to all assignees will send email to all related persons , so uncheck it .
instead , select the recipient owner . (supposing the person who created the document is the one who is asking for leave).
write your message , for example :
Dear {{doc.employee_name}},
your application is approved … and add more details .

I have already created an email template and added as default email template to leave application form in Customize Form. In that case do I need to select Channel as Email or System Notification.

If I select email, then will it send two emails? One from email template and one from Notification message?

Or I can simply create notifications with custom message and select channel as email and enable system notification. Without relying on Email Templates we can use Notifications to send emails and system notifications?

I am confused with the flow. Can you explain flow for leave request
