Issues with Fullscreen-Webwidget on iOS mobile

Unfortunately, the WebWidget SDK is automatically fullscreen on any mobile device, which means that on iPhone X and later devices (with the top nodge) the minimize Button cannot be clicked anymore and the title is covered entirely by the device's nodge.

I have tried offset, but that just displaces the whole thing vertically which means the send button at the bottom can no longer be clicked. 

Please tell me what I can do, so it is no longer full screen or can have some padding/margin etc. so that it only takes up 80% of the viewport height or something.

Best regards,
