Facebook Pixel Modification on Shopify Collection

I'm seeking a Shopify expert to modify the Facebook Pixel in a specific collection of my store. The pixel is already set up, so no installation is necessary. The work will involve direct changes to the Shopify theme code.

Key Requirements:
- Proven experience with Shopify theme code
- Expertise in Facebook Pixel
- Ability to implement changes directly in the code

Please ensure you have relevant experience before bidding. Thank you!
