forceActivate method is not working

[KateDorofieieva]

I'm trying to call ForceActivate like this :
this.serviceWorker.on('waiting', (registration) => { if (window.confirm('New version available! Refresh?')) { this.serviceWorker.forceActivate(registration); } }); but it fails with error :
service-worker.js:19 Uncaught (in promise) TypeError: this.serviceWorker.forceActivate is not a function
at ServiceWorker. (service-worker.js:19:1)
at sendEvent (index.js:219:1)

at ServiceWorker._waiting (service-worker.js:145:1)
