async def from_interaction(cls, interaction: Interaction, /) -> Self:
"""|coro|
Creates a context from a :class:`discord.Interaction`. This only
works on application command based interactions, such as slash commands
or context menus.
On slash command based interactions this creates a synthetic :class:`~discord.Message`
that points to an ephemeral message that the command invoker has executed. This means
that :attr:`Context.author` returns the member that invoked the command.
In a message context menu based interaction, the :attr:`Context.message` attribute
is the message that the command is being executed on. This means that :attr:`Context.author`
returns the author of the message being targetted. To get the member that invoked
the command then :attr:`discord.Interaction.user` should be used instead.
.. versionadded:: 2.0
Parameters
-----------
interaction: :class:`discord.Interaction`
The interaction to create a context with.
Raises
-------
ValueError
The interaction does not have a valid command.
TypeError
The interaction client is not derived from :class:`Bot` or :class:`AutoShardedBot`.
