I want that if the author's messages are above the bot role, then the event will not work accordingly, how can I do this? Here is my code:

async def on_message(message):
    if message.author== bot.user:
        return
    if message.author.top_role != bot.user:
        return
    elif message.content.startswith("text"):
        channel= message.channel
        await message.channel.send(f"{message.author.mention} text")
        await message.delete()
    await bot.process_commands(message)
