Getting CORS error while calling zeebe tasklist API's from custom angular tasklist application

I am creating a custom angular tasklist application. for that I am using tasklist API’s. but I am gettting CORS error while calling tasklist API from my angular application. I had uploaded my project structure.

for now I am only using elasticsearch, zeebe, tasklist, and operate.

used API’s →
1. (POST) - http://localhost:8080/api/login?username=demo&password=demo

2. (POST) - http://localhost:8080/v1/tasks/search?TASKLIST-SESSION=D9A769CF1C7DB0725A9C5246C6BBA518

3. (GET) - http://localhost:8080/v1/forms/userTaskForm_0ludier?processDefinitionKey=2251799813685588

1st API return the tasklist-session in header which I am using for calling the 2nd and 3rd API.

I am not getting how to enable cross origin requests coming from http://localhost:4200 in zeebe tasklist

elasticsearch version - 7.16.2
zeebe version - 8.3.0
tasklist version - 8.3.0

So @NEWTOZEEBE , did you manage to solve the problem?
