Getting error while upgrading Enigma JS version (12.20) in my web app integrated with Qliksense (September 2019)

While upgrading Engima Js in web code, I am getting errors related qlik engine backend services.

Please find below error log :

Error: libs/shared/enigma/src/lib/helpers/enigma-helper.ts:12:34 - error TS2339: Property 'create' does not exist on type 'typeof import("enigma.js")'. 

Error: libs/web-app/shared-services/src/lib/enigma/enigma.service.ts:231:42 - error TS2339: Property 'config' does not exist on type 'Session'.  

    console.log(`Connecting to ${session.config.url}`); 

Error: libs/web-app/shared-services/src/lib/enigma/enigma.service.ts:249:30 - error TS2339: Property 'openDoc' does not exist on type 'QixObject'. 

   const app = await global.openDoc(appId); 

 Do I need to even upgrade Qliksense to make it work or there is some other way to fix this?
