### Description

Using an embedded iFrame of RocketChat on my website, previously I was using detection of the `startup` iFrame event to run a login script. However, now it seems unable to get the `startup` event through, but still RocketChat is sending through the `Custom_Script_Logged_Out` event.  
Does anyone know why I might not be getting the `startup` event anymore? As per RocketChat’s docs, it’s simply an event fired when the iFrame initialises.

I was on Rocket.Chat version 7.13.2 but have since upgraded to 8.4.0 and also done the necessary changes to MongoDB moving it away from 6/7 on bitnami to the official image for 8.2.7. This doesn’t appear to have made any change for the above issue.

Many thanks in advance for any help!
