Tasklist: Configuration of AngularJS application

I’m beginner in AngularJS. For several reasons I need to extend the configuration of the AngularJS application. For example as mentioned in https://www.codingpot.com/2017/12/stripe-payment-integration-in-angularjs.html to set the publishable Key in a Stripe Payment Integration.

Is this possible with Embedded Forms in Taskslist or is this only possible, if one develops his own tasklist application?

It is possible to configure the angular application by means of a custom config.js file: https://docs.camunda.org/manual/latest/webapps/tasklist/configuration/#custom-scripts.

The location of config.js depends on the Camunda version, for spring-boot see Spring Boot: Replace config.js for Webapps-Configuration
