How to make discord.py bot respond to spoiler text messages?

Question

I was attempting to make my discord bot respond to messages even if it is spoiler marked by users. For example if a user were to send ||Hello|| I would still want my bot to respond.

Here is some relevant code

@client.listen ("on_message")
async def hello_message (message):
  if message.content.startswith ("Hello there!"):
    await message.channel.send ("Hello! it is nice to see you")

I tried doing something like this

@client.listen ("on_message")
async def hello_message (message):
  if message.content.startswith ("||Hello there!||"):
    await message.channel.send ("Hello! it is nice to see you")

But that does seem to work.

Also note that I put client.listen so that the bot could respond to other commands.

Any help would be appreciated.
