How to keep track of phone calls & emails made through Dynamics 365 mobile app?

Hello Experts,

Let's take one scenario, where I've made one email/Phone call from Dynamics 365 mobile app for one contact, now how to automatically keep track of this email/Phone call activity in CRM activity?

Is there any way through which activity will be created for the email/Phone calls made through the Dynamics 365 mobile app?

Thanks,

Herry
