Assistance with Customizing Checkout Layout

Hello WoodMart Support Team,
I need your assistance with customizing the checkout page to better meet my requirements. Specifically, I would like to:
Add additional fields:
– “Unique Registration Code (CUI)”
– “Company Name”
– “CIF” (Company Identification Number)

Set certain fields as required:
Phone Number (now its optional)

I have attempted to use various plugins, including ‘Flexible Checkout Fields for WooCommerce’ and ‘WooCommerce Checkout Manager’, to achieve these changes. However, despite configuring the new fields through the plugin, the changes did not reflect on the actual checkout page.

Thank you for your support, and I look forward to your response.
