ok for this you want to use hte “pro” features of carbide create (one year code available as promo somewhere)
basically what you do in a program like gimp is make a grayscale image where black is the bottom and white is the top. so you make everything but the text black, and the text you make a “fade from white to almost black” fill… and you will pretty much get this. You will need to do some work on the CC side, similar to the steps in
but start at step 3 (step 1 and 2 are about getting that grayscale image )
you can do all kinds of variations on how to slope the text, just by controlling how exactly you do the gradient fill
