I get an ERROR in ../node_modules/@ng-idle/core/lib/eventtargetinterruptsource.d.ts:29:9 - error TS1086:
An accessor cannot be declared in an ambient context.
at compile time.

Can avoid it by setting the "skipLibCheck": true, in tsconfig , but not a desired setting.

"peerDependencies": {
"@angular/animations": "^8",
"@angular/cdk": "^8",
"@angular/common": "^8",
"@angular/core": "^8",
"@angular/forms": "^8",
"@ngx-translate/core": "^11",
"rxjs": "^6"
},
"dependencies": {
"@ng-idle/core": "10.0.0-beta.1",
"@ng-stack/forms": "^1.3.4",
"js-uuid": "^0.0.6",
"moment": "^2.24.0",
"ng-click-outside": "^3.3.0",
"tslib": "^2.0.3"
},
"devDependencies": {
"@babel/generator": "^7.11.6"
}

Anyone else had this one?
