[FEATURE] Mixed Visibility and Additional Poll Modes within Live Poll

[RonLek]

Mixed Visibility and Additional Poll Modes need to be extended to Live Poll.

Challenges To Be Worked Upon
For single polls, Mixed visibility modal pops open right after the user clicks submit what would the flow be like in case of Live Polls where clicking "Next" immediately opens up the poll modal for the next poll in line? A user flow needs to be designed in this regard.

A challenge within additional poll modes is to attach the added option to that particular poll itself. An edge case to handle is what if a user is adding an option to a live poll and it ends before the user has submitted?
