Changing the Text on the Shop Pay Checkout page?

[LeeAurich]

Due to a quirk of how we’ve had to set up our shop, we’ve needed to change the word “Shipping” on all our checkout pages to “Handling Fee”. I’ve done this successfully through the Settings - Checkout - Manage Checkout Language section for all pages except for the Shop Pay page.

Does anyone know how to specifically edit the text on the Shop Pay checkout/payments page. I couldn’t find a related field in the “Manage Checkout Language” section mentioned above.

This is what the current Shop Pay page says:

This is what I want it to say:

Hi Moeed,

I’ve tried your solution but it hasn’t worked for me, not sure if I’m doing something wrong.
This is where I’ve pasted the code in theme.liquid (Where it says “<---- Pasting Here”)

But no change to the shop pay screen as you can see:
