Venu 3 Shifting Capabilities

I'm wondering why  the Venu 3 doesn't have shifting capabilities .

On the Garmin " This in Ant" website it says cycling is one of the activities for Venu3  .

The watch doesn't have shifting but it does have LEV (light electric vehicle) capabilities   .

Why can't we chose the options we want ?

Only Fenix and Forerunner have shifting capabilities .
