If the browser/HTML spy mode is serving your purpose, the mentioned command won't be necessary.
When the command '--force-renderer-accessibility' is appended to a URL, it turns on most (if not all) of the Accessibility Modes in the tab where the concerned URL is opened. It also enables UIA mode to spy on the browser elements.
When you are using the command, append it at the below mentioned areas:
1. App modeler where we mention the URL
2. In any data item which you may use to store the URL to be opened.
Please find the link below for more details on --force-renderer-accessibility:
