How do I make it so my discord bot only take inputs from the person that started the command

Question

    @client.command()
    async def submitcluetest(ctx):
         await ctx.send(f"{ctx.author.mention}Check your dms!")
         await ctx.author.send('Submit your answer here, all lowercase. Do not reveal this to anyone else if you got it right, everyone who solves it gets a special role :smirk:')
         message = await client.wait_for('message')
         if message.content == 'twopeople':
         await ctx.send('correct answer')
     else
         await ctx.send('try again')

This is my code right now. The problem is that once someone starts the command and tries to input their answer, someone else could type something and interrupt them. I would like message.content only be detected by the user. I tried using message.author.content or author.message.content but that still wouldn't work.

I hope the below code helps to fix your problem

@client.command()
async def submitcluetest(ctx):
     def check(m):
          return m.author == ctx.author and m.channel == ctx.channel
     await ctx.send(f"{ctx.author.mention}Check your dms!")
     await ctx.author.send('Submit your answer here, all lowercase. Do not reveal this to anyone else if you got it right, everyone who solves it gets a special role :smirk:')
     try:
          message = await client.wait_for('message', timeout=120, check=check)
     except asyncio.TimeoutError:  
          await ctx.send("You didn't entered in time.Please answer at next time!")
          return
     else:
          if message.content == 'twopeople':
            await ctx.send('correct answer')
          else
            await ctx.send('try again')

Use a lambda expression for the check. message = await self.client.wait_for('message', check=lambda m: m.author == ctx.author)
