Road Warrior setup using IKEv2 with RSA authentication with client internet over office pulic IP

Hello,
I have read this article and can’t find the solution for all traffic via office router to internet
https://wiki.mikrotik.com/wiki/Manual:IP/IPsec

My goal is to see LAN devices in office but also when I type
http://www.whatismyip.com to receive (public IP from my office)

following this part of web site
https://wiki.mikrotik.com/wiki/Manual:IP/IPsec#RoadWarrior_client_with_NAT
I see LAN but all other traffic go via my phone LTE directly.

There should be a setting in your phones vpn settings to send all traffic through the vpn. This is controlled on client side.
