Current behavior:

I'm trying to disable some dates dynamically but it's not working, it is disabling dates only when we set disable dates at the time of variable initialisation.
-----------Following is Working----------------
options: CalendarModalOptions = {
daysConfig: [
{
date: new Date(2021, 3, 12),
disable: true,
},
{
date: new Date(2021, 3, 15),
disable: true,
}
]
};
-----------Not Working---------------
this.options.daysConfig = [{
date: new Date(2021, 3, 12),
disable: true,
}, {
date: new Date(2021, 3, 15),
disable: true,
}];

Expected behavior:

You can try to replace whole options, works for me, smth like -

this.options = {
    ...this.options,
    daysConfig:  [{
        date: new Date(2021, 3, 12),
        disable: true,
    }, {
        date: new Date(2021, 3, 15),
        disable: true,
    }],
};
