How to create sub entry points of angular using Angular CLI?

Question

my goal is to create angular library with:

1. npx ng g library mycomp/ui/<library> or alternatively
2. npx ng g module mycomp/ui/<library>

Attempt #1 with npx ng g library Command to run

npx ng g library mycomp/ui/my-app-profile --dry-run

Error produced

Schematic input does not validate against the Schema: {"name":"mycomp/ui/my-app-profile"}
Errors:

  Data path "/name" must match pattern "^(?:@[a-zA-Z0-9-*~][a-zA-Z0-9-*._~]*/)?[a-zA-Z0-9-~][a-zA-Z0-9-._~]*$".

Attempt #2 with npx ng g m

Command to run

npx ng g m my-app-profile --project @mycomp/ui --dry-run

produced

CREATE projects/mycomp/ui/lib/my-app-profile/my-app-profile.module.ts (198 bytes)

NOTE: The "dryRun" flag means no changes were made.

the problem is, the module gets created in lib/ instead of projects/mycomp/ui/my-app-profile/src/my-app-profile.module.ts
