The following steps illustrate how to configure clear button in Calendar UI.

On created event of Calendar add the required elements to have clear button. Here we have used div with Essential JS 2 Button component.
Use the e-footer class to the div tag to act as the footer.
And use the button to clear the selected date.
Bind the required event handler to the button tags to update the value.

        clearBtn.setAttribute('class', 'e-btn e-clear e-flat');
        clearBtn.innerHTML = 'Clear';
        const footerElement = document.querySelector('.e-footer-container');
        footerElement.insertBefore(clearBtn, footerElement.childNodes[0]);
        document.querySelector(".e-clear").addEventListener("click", (e) => {
            proxy.value = null;
        });
