To have the text @here calling all the @Member of a channel, so they have notifications for these messages

@channel is used for this already.
How @here works in slack for example is that only members who are active/online will get the notification. For this use case there is another uservoice here: https://microsoftteams.uservoice.com/forums/555103-public/suggestions/40821214-add-functionality-for-here-mentions
