Sous Angular 15, je veux utiliser geoportal-extension mais il y a des erreurs dans la librairie

je créé un nouveau projet angular. puis npmi leaflet@1.7.1 puis npm i geoportal-extensions-leaflet

package.json :

  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "watch": "ng build --watch --configuration development",
    "test": "ng test"
  },
  "private": true,
  "dependencies": {
    "@angular/animations": "^15.0.0",
    "@angular/common": "^15.0.0",
    "@angular/compiler": "^15.0.0",
