Playwright Browser Load testing lack of configuring dynamic browser context with Artillery

[MariaStadnik]

I'm using Artillery for browser load testing and am struggling with how to configure dynamic contexts for each test scenario. Specifically, I need to set extraHTTPHeader for my browser dynamically without hardcoding token values. I want each scenario to create its own context that includes a unique authorization token, so each test can authenticate individually.

Currently, I can't find a way to pass a new token for every scenario without embedding the token directly in the configuration. Is there a method in Artillery to dynamically generate or fetch tokens per scenario, or to set headers on a per-scenario basis before the browser context is created? I also don't want to store the hardcoded token value in my repository anywhere, so would like to utilize a mechanism of retrieving a token value dynamically via some js function.

Here is my Artillery yaml below:

  target: 'myTargetUrl'
  phases:
    - duration: 10
      arrivalCount: 2
      name: phase-for-ui-test
  engines:
    playwright: 
      extendedMetrics: true
      launchOptions:
        headless: false
      contextOptions:
        extraHTTPHeaders:
          Authorization: 'Bearer myTokenValue
  processor: 'processor.js'

scenarios:
  - engine: playwright
    testFunction: 'myTestFunction'

Thanks for any help
