IBM Mobilefirst V8 - Custom Direct update on hybrid application using Ionic v3.20.0 is not happening - ibm-mobilefirst

Question

I am trying to implement customized direct update in ionic v3.20.0 but while accessing to the below code, am unable to proceed. I can't find any way to do it as the below function is not there in worklight.d.ts file,but can be found at worklight.js file.
The plugin used is cordova-plugin-mfp. The solution provided in the official doc is relevant to only cordova application,that can be done through index.js file which has the function WlCommonInit(). As per the doc the below code is to be called from this function, but unable to do this in ionic-cordova based application.
wl_DirectUpdateChallengeHandler.handleDirectUpdate = function(directUpdateData, directUpdateContext) {
// Implement custom Direct Update logic
};
Pleas refer to the below link for further information.

Please help me to implement this in ionic v3.20.0 which need to be implemented in typescript. Thanks!.

Presently there is no typescript API for wl_DirectUpdateChallengeHandler in cordova-plugin-mfp to customize direct update in Ionic Applications.
However you can do implementation in the JavaScript and include it in the Ionic Project. Following are the steps :
Create a folder called js inside the path src/assets of the project
Create a new JS file with following code and save it as wldirectudpate.js
function wlCommonInit() {
console.log(">> wlCommonInit() ..." );
wl_DirectUpdateChallengeHandler.handleDirectUpdate = function(directUpdateData, directUpdateContext) {
// Implement custom Direct Update logic
};
};
Add the JS location in index.html file which is located at /src/index.html
<script src="assets/js/wldirectudpate.js"></script>
