Question

Python

An error in the code. Python, aigram. It turns out here is such an error (attached file), how to fix it?

Here is the same code:

@dp.message_handler(is_admin=True, commands=["unmute","унмут"],commands_prefix="!/")
async def cmd_unmute(message: types.Message):
  if not message.reply_to_message:
    await message.reply("Эта команда должна быть ответом на сообщение!")
    return

    await bot.restrict_chat_member(message.chat.id, message.reply_to_message.from_user.id,ChatPermissions(
                                        can_send_messages=True,
                                        can_send_media_messages=True,
                                        can_send_other_messages=True,
                                        can_add_web_page_previews=True))

Somewhere spaces were used, somewhere tabs were used as indents, replace everything with one thing
