Long steems issue

Hi everyone! I've got this beautiful manjula, resurrected from a bad care situation (got her half price💚), now she's super healthy giving beautiful big leaves.

The only question is, as you can see I have those 2 long steems that I pitched in the ground (with just 2-3 roots as a result), and I would like to propagate it without damage the main leaves, my question is, , where I have to cut? because if chop the top part (It has like 5-6 leaves) will it survive and radicate in water? or it's too big?

thanks in adviceeee🍃
