Telegram Channel Message Forwarding Enhancement

I have an existing setup that automatically forwards messages from a specific Telegram channel to my own. I need a small tweak: a button that appears under each auto-forwarded message. Upon being pressed, this button will redirect the user to a specific webpage or telegram channel.
I attached image files what i require.

Requirements:
- Modify the existing code to incorporate a button under each auto-forwarded message.
- Ensure that pressing the button redirects to a specified URL.

Skills and Experience:
- Strong understanding of Telegram's API and bot development.
- Proficient in the programming language used in the existing script.
- Experience in modifying and enhancing existing code.
