It is impossible to bring into the angular library the code that uses Form, ApplicationRaf and other components. There is always an error:

TS2345: Argument of type
import("/Users/.../project1/frontend/node_modules/@angular/core/index").ApplicationRef
is not assignable to parameter of type
import("/Users/.../project2/ngx/node_modules/@angular/core/index").ApplicationRef
Types have separate declarations of a private property _destroyed

Why do you think it's not your fault?

The library project and project 2 use the same version of angular, and an object of the same type is passed, but for some reason this causes an error.

Consider fixing this, or at least suggest good workarounds.
Currently, objects can only be send to lib by assigning them the any type.
