Thanks for the tip. This worked:

const dialogContents = `
    <sp-heading>Help</sp-heading>
    <sp-divider></sp-divider>
    <sp-body>Some text</sp-body>
`;

const dialog = document.createElement('DIALOG');
dialog.innerHTML = dialogContents;
document.body.appendChild(dialog);

dialog.uxpShowModal();
