How to use an SAPUI5 application in another one as component (without duplicating the whole code of the application)?

Environement

Framework : SAPUI5 V1.38.39
IDE : SAP WEB IDE

Problem

I want to use a SAPUI5 application in another one, in order to do so I found the following resource: https://blogs.sap.com/2017/04/05/sapui5-how-to-reuse-parts-of-a-sapui5-application-in-othermultiple-sapui5-applications/

Code

in component.js in init I used :

var sPath = sHostUrl.includes("webidetesting") ? "https://gtyext.net" : sHostUrl;
jQuery.sap.registerModulePath("ztntapp", `${sPath}/sap/bc/ui5_ui5/sap/ztntapp/`);

And in my view :

<core:ComponentContainer 
    name="ztntapp" 
    manifestFirst="true" 
    component="ztntapp">
</core:ComponentContainer>

and in neo-app.json

{
    "path": "/sap/bc/ui5_ui5/sap/ztntapp/",
    "target": {
        "type": "destination",
        "name": "gtyext_net",
        "entryPath": "/sap/bc/ui5_ui5/sap/ztntapp/"
    },
    "description": "namespace.tntapp Resources"
}

Error message

Uncaught Error: failed to load 'ztntapp/Component.js' from https://webidetesting278-a392f.dispatcher.hana.ondemand.com/sap/bc/ui5_ui5/sap/ztntapp/Component.js: Error: failed to load 'TrackAndTrace/ztntapp/model/models.js' from resources/TrackAndTrace/ztntapp/model/models.js

Points with neo-app.json :

• the application "ztntapp" itself works outside this application
• the path for component.js is https://webidetesting278-a392f.dispatcher.hana.ondemand.com/sap/bc/ui5_ui5/sap/ztntapp/Component.js however the path for model somehow become https://webidetesting278-a392f.dispatcher.hana.ondemand.com/webapp/resources/TrackAndTrace/ztntapp/model/models.js (I am not sure why "webapp/resources")
• https://webidetesting278-a392f.dispatcher.hana.ondemand.com/sap/bc/ui5_ui5/sap/ztntapp/model/models.js is found, resource should probably be loaded from here instead of /webapp/resources/TrackAndTrace/ but I don't know how to do so

Other research

• With the neo-app.json file, the problem is to locate the resource from the "ztntapp", I seen that there is also a jQuery.sap.registerResourcePath but I am not sure how to use it for this case
