How to hide sender's name when forwarding a Telegram message?

Hi,

I would like to broadcast messages that I forward to my Telegram bot, starting with a trigger phrase like “publish,” to the chats and groups where the bot has admin access. However, I want to hide the sender’s name.
The Telegram forward module doesn’t offer many options, such as hiding the sender’s name or editing the text to remove the trigger word. I tried using the “send message” module and included the entire “message” block as text, but it generated an error because my message included an image with a caption.

Please help me achieve these two goals: hiding the sender’s name and removing the trigger word. Thank you.
