After Angular 16 upgrade, throws errors for library mydatepicker and angular2-virtual-scroll not compatible with Angular ivy

Question

I have upgraded my project from Angular 15 to 16 And im using these two libraries

"mydatepicker": "^9.0.2",
"ngx-virtual-scroller": "^4.0.3",

But on ng serve both these libraries throws

 node_modules/mydatepicker/lib/mydatepicker.module.d.ts:1:22
    1 export declare class MyDatePickerModule {
                           ~~~~~~~~~~~~~~~~~~
    This likely means that the library (mydatepicker) which declares MyDatePickerModule is not compatible with Angular Ivy. Check 
if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the 
library is expected to be compatible with Ivy.

This likely means that the library (ngx-virtual-scroller) which declares VirtualScrollerModuleis not compatible with Angular Ivy. Check 
if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the 
library is expected to be compatible with Ivy.

Tried this script in Package.json as well

"postinstall": "npx --package @angular/[email protected] --yes ngcc"

Not working still same error cmg on ng serve.

Any way to make these libraries work with Angular 16
