Cypress Not Finding Dynamic Text

I ran into a situation today where Cypress was not finding some text that was added dynamically to the DOM after page load using jQuery. Here is my initial attempt:

it('displays the total amount', () => {
	cy.get('#total-amount').contains('$100.00');
});

And here is what finally worked:

it('displays the total amount', () => {
	cy.get('#total-amount').then(($elem) => {
		assert($elem.text() === '$100.00');
	});
});
