Cannot use "Send a direct invite" via. Mobile app iOS & Android

App version: iOS 2.11
Mattermost Version: 9.3.0

Adding someone via e-mail does work on dekstop but I cannot find the option if I hit the + button on my mobile app.

According to the documentation this should be possible right?

I’ve checked the Anroid app too, also not possible in the Android app.

Does anyone know if this should be possible in the mobile app?
