Use the outline, rewrite the prose
The most valuable output here is the thesis and the outline, not the draft. A thesis that takes a position — rather than announcing a topic — is the single thing that separates an essay that argues from one that describes, and it is the part students most often get wrong before writing a word.
Submitting the draft as it stands is a bad idea for two separate reasons, and only one of them is about getting caught. Every university treats submitting generated text as your own as misconduct, and the penalties run from a zero on the module to a bar from the examination. Read your institution's policy rather than assuming.
The slower cost is the one nobody warns you about. An essay is where you learn to hold a position for 2,000 words, and a degree keeps testing that skill — in the viva, the closed-book paper, the dissertation. Outsourcing the first three essays leaves you unable to write the fourth, with less time to learn.
