Counts the number of submissions belonging to the specified forms.
The countSubmissions() function is useful for analytics and tracking purposes. For example, if you have a contact form on your website, you can use this function to track how many submissions it receives daily, weekly, or monthly.
You can only call this method when authenticated as a Wix app or Wix user identity.
Form IDs which submissions should be counted.
The app which the form submissions belong to. For example, the namespace for the Wix Forms app is wix.form_app.form. Call getSubmission() to retrieve the namespace.
