Safari blocking scripts from loading due to security if there is an iframe inside?

Question

JavaScript

There are two scripts on the page that load the chat widget.
This widget works on all browsers, including opera, edge, google, yandex.
The only browser that doesn't work is safari. I'm assuming it doesn't load a 3rd party library due to its dumb security.
Here is the error that is displayed in the console after connecting:

The widget itself (layout) is generated, but if you click on it, then 0 reaction.
At the same time, this widget on the iPhone works correctly.
How to fix?
