Test Scenarios

from interactions import slash_command, SlashContext, Poll, PollMedia

@slash_command()
async def test(ctx: SlashContext):
    # method 1
    poll = Poll.create("Test?", duration=1)
    poll.add_answer("Yes!")
    poll.add_answer("No.")

    # method 2
    poll = Poll.create("Test?", duration=1).add_answer("Yes!").add_answer("No.")

    # method 3
    poll = Poll.create("Test?", duration=1, answers=["Yes!", "No."])

    # method 4 (mostly for emojis)
    poll = Poll.create("Test?", duration=1, answers=[PollMedia.create(text="Yes!"), PollMedia.create(text="No.")])

    await ctx.send(poll=poll)
