Alternatives for prefix command for polls

[Comeza]

It's quite inconvenient to write the bot a private message to vote on a poll.
So the bot could use some alternatives:

• Bot Buttons
  Has also the advantage that the button is directly linked to a poll, so you don't have to enter a poll id

• Reactions
  Could be used if there are more poll options than the bot can create buttons for. But also has the disadvantage that you would have to keep track of which emojis are allowed and which are not.
