How to do the email sending process through background processing by using UI Pages within portal without using case type
I have the requirement to send auto generated login credentials to the registered users for their email but I am building the user registration by the admin in admin portal (UI Pages) without using the case type.
I tried with the query processor by calling a button and calling the flow action through simpleEmailNotification activity but I didn't succussed.
Can I have any suggestion for it or any correct way to do it or any alternative ways.
