ngx-daterangepicker-material 从开始日期起禁用 n 天

Question

我在 angular 9 项目中使用 ngx-daterangepicker-material 作为日期选择器。我有要求，当用户 select 的开始日期从开始日期到未来和过去超过 60 天时，不应 selectable

例如，如果用户 select 开始日期为 2021 年 1 月 1 日，结束日期介于 2021 年 3 月 1 日（未来 60 天）和 2020 年 11 月 1 日（60 days past) 不应该 select 对用户可用。其余所有结束日期应为 selectable

尝试使用 minDate、maxDate 来实现，但无法实现。

提前致谢！
