Session Replay recording without agent in top frame

When the parent doesn't contain the RUM JavaScript, IFrame recording works when the JavaScript tag property srif=1 (stands for "Session Replay IFrame recording") is added in the application settings. Select Capturing > Advanced setup > Custom configuration properties.
