How setup own VPN app creat and import WG tunnel automatically

Dear Expert
If I install the Wireguard app on my mobile phone, I need to manually scan the QR code or Import a WG tunnel to access the VPN.
I want users to download the Wireguard app and it can create a new peer import tunnel from the Mikrotik router automatically (installation).
like Nord VPN or Wireshark VPN.
or
user downloads the application from the Play Store. This app directly connects with Mikrotik, creates a new peer in Wireguard, and imports a tunnel.
How can be possible?
What do I need to do?
Thanks

The MT router can provide 1 QR codes or config file for that special client that is remote.

I believe but not certain, the way to create multiple accounts ( Qr codes or config files) is from the BTH app on your smart phone.
Step1: Create a BTH tunnel on your smartphone while behind the MT router aka locally.
Step2: Create shared accounts by using the BTH app and “MANAGED SHARES” and send produced qr code or config file over whatever medium (email, discord etc..)

I understand. But you know some users didn’t know how to attach configuration files to the app. people want to install and use on a few clicks
like other apps such as NordVPN and Wireshark.

Well the instructions are not difficult.
Open BTH app on smartphone and import QR code.
It will be up to you to make easy follow instructions for users.
Suggest you try it a couple of times to figure out how best to describe it to users
