How can I change the 'Submit' button to 'Add to Cart' in the Startup theme?

Store Design

I am using Shopify theme “Startup” version 9.6.0. The variant products have Add to cart buttons and non-variants have Submit buttons.

I want to change Submit button to Add to Cart Button for non-variant products too. On inspecting code, I discovered that the input value is missing for the Submit buttons. Where can I add the input value to these buttons?
