Angular not Compiling with ngx-device-detector with Angular 9.x

I cannot run ng serve since I updated ngx-device-detector.

Previous Version "ngx-device-detector": "^1.3.20"

New Version "ngx-device-detector": "^2.0.7"

The new version is causing the error

Compiling ngx-device-detector : module as esm5 [33mWarning:[ 0m Invalid constructor parameter decorator in /node_modules/ngx-device-detector/fesm2015/ngx-device-detector.js: () => [ { type: undefined, decorators: [{ type: Inject, args: [PLATFORM_ID,] }] } ] Error: Error on worker #2: Error: getInternalNameOfClass() called on a non-ES5 class: expected DeviceDetectorService to have an inner class declaration

I used it with two projects (Angular 11 & 12) in this month. Works well. It’s probably about Angular 9.

Closing the Issue because it seems to be a version incobatibility between Angular 9.x and ngx-device-detector != 1.4.1.

For anyone stumbling across this, please use version 1.4.1 with Angular 9 as it is documented in the readme. Thanks @AhsanAyaz for clarification
