By default, this field is required on the record page. However, when we retrieve the MDT, it appears as None, and we cannot mark it as required from the Page Layout because it is a standard field.
This field will always have the current value as the default. Although a Null value can be selected, it will automatically be replaced with the default value.
To make the field required, we can retrieve the MDT and mark the field as required there, which will add the asterisk (*) indicator on the page.
