Mobile app - Create Account Feature

Hi, while exploring options to onboard users in Mattermost, it’s observed that the feature to “Create Account” & join the team shows up only in web and not in mobile clients. Is this a feature scheduled for a future release of mobile app or is there a reason for restricting the feature in mobile? I understand that options of email invite and team invite url exists but is curious to find an option to avoid users to go via web for the registration purpose. Please advice.
