discordpy 2.0 interaction is a required argument that is missing

@client.command(brief="Send a message with a button!")
async def button(ctx,interaction: discord.Interaction):
    view = discord.ui.View()
    style = discord.ButtonStyle.gray
    item = discord.ui.Button(style=style, label="Read the docs!", url="https://discordpy.readthedocs.io/en/master")
    view.add_item(item=item)
    await interaction.response.send_message("This message has buttons!", view=view)
    await interaction.response.send_message(content="Hi", ephemeral=True)

discord.ext.commands.errors.MissingRequiredArgument: interaction is a required argument that is missing.

Actually i just want to send a message by intraction, but seem itwasn't work :(

我认为你对基本概念有些混淆，因为你的代码混合了命令和交互的内容。&lt;br&gt;
如果你想创建按钮，就不能像 `@client.command` 那样以旧的命令方式编写。你需要使用 `应用命令` 或 `混合命令`（即交互和命令的混合方式）&lt;br&gt;
所以，你不应该同时有像 `(ctx: Context, interaction: Interaction)` 这样的内容。&lt;br&gt;
而且，传统上，你需要创建一个 `view` 类并在这个 `view` 类中创建一个按钮。然后，当你将消息或嵌入发送给用户时，你可以将这个视图附加到其中。&lt;br&gt;
如果你想在应用命令中多次回应用户，你不能通过 `interaction.response` 来做到（只能回应一次）。你可以使用 `interaction.followup()` 来进行后续的回应。[链接](https://discordpy.readthedocs.io/en/stable/interactions/api.html?highlight=followup#discord.Interaction.followup)&lt;br&gt;
关于视图示例，请参考 [此处](https://github.com/Rapptz/discord.py/tree/master/examples/views) 下的示例文件。&lt;br&gt;

I think you are confused about the basic concepts since your code is mixed up command and interaction stuffs. &lt;br&gt;
If you want to create button, you cannot write in the older command way like `@client.command`. You need to either use `application command` or `hybrid command` (which is a mix of interaction and command)&lt;br&gt;
So, you should never have something like `(ctx: Context, interaction: Interaction)` together.&lt;br&gt;
Also, classically, you need to create a `view` class and create a button inside this `view` class. Then you can attach this view to your message or embed when you send this to the user. &lt;br&gt;
And, if you want to respond to user multiple times in a application command, you cannot do that through `interaction.response` (only once). You can use `interaction.followup()` for later responses.
