Hi @anjan and all, just saw this post.
FYI I have recently followed the instructions in the " E-mail Notifications (Microsoft Flow)" section of the UNHCR KoBo tips/tutorial and it works well to get automatic email notifications to an email address (either to your own email address, or by following rules). This could be a good option to try? The UNHCR page is linked from the below thread, many of the examples reference UNHCR server/setup but can easily be adapted for the rest of us!
I didn’t manage to figure out a way to attach the whole submission at once (e.g. as a pdf) but you can certainly set up an email notification and individually list the field values separately in the body of the email.
