Schedule online meetings (SFB or Teams) using Outlook Mobile

I have a user that is SFBO (SFB Hybrid) and EXO (EXCH Hybrid), which wants to schedule an online meeting, in this case SFBO, using Outlook Mobile (iOS) but he doesn’t get the option in the Outlook Mobile client. My question is, should it work ?

And if yes, why user doesn’t sees this option in the outlook mobile client?
