webhook message doesnt trigger publish | disnake | Page 1

Hi, i have the following code to trigger a publish in a new channel:

        channel = bot.get_channel(env_variable.TECH_NEWS_ID)
        message = await channel.fetch_message(channel.last_message_id)
        await message.publish()
        return

Now it works when i manually enter a message in that channel, but it doesn't work when that message is a webhook. Is this possible?
