@@ -4,11 +4,11 @@ Here, we will discuss the `DynamicFetcher` class (formerly `PlayWrightFetcher`).
 
 As we will explain later, to automate the page, you need some knowledge of [Playwright's Page API](https://playwright.dev/python/docs/api/class-page).

 ## Basic Usage
 You have one primary way to import this Fetcher, which is the same for all fetchers.

-In session classes, all these arguments can be set globally for the session. Still, you can configure each request individually by passing some of the arguments here that can be configured on the browser tab level like: `google_search`, `timeout`, `wait`, `page_action`, `extra_headers`, `disable_resources`, `wait_selector`, `wait_selector_state`, `network_idle`, `load_dom`, and `selector_config`.

 This is where your knowledge about [Playwright's Page API](https://playwright.dev/python/docs/api/class-page) comes into play. The function you pass here takes the page object from Playwright's API, performs the desired action, and then the fetcher continues.
