Shortcuts: Overlay File Name on Image

I need your help! I have been trying to make my first ever shortcut and failing.

For my business I share a lot of images via email where the image file has details of my products. But as everything is moving more and more to WhatsApp I need help in Generating images where the file name is over layer as a text (preferably with a white txt box around it)

I tied these steps by chatgpt but the result is a txt file not an image file

🧩 Action 1: Get File(s)

• Search for and add: Ask for Files
• Enable "Select Multiple" if needed.
• (Optional) Filter by file type (like .jpg, .png)

🧩 Action 2: Get File Name

• Add: Get Name from the "Files" category.

🧩 Action 3: Convert Image to Editable Format

• Add: Get Image from Input

🧩 Action 4: Add Text to Image

• Add: Overlay Text
• Tap on "Text" and select "Name" from previous step
• Choose the position and font size you prefer

🧩 Action 5 (Optional): Save Image

• Add: Save File
• Choose where to save the edited image

where am I going wrong!

I could run this on a Mac or iPhone and having both options would be great
