[Chat Widget] - Is it possible to enable the attachment icon for certain journeys (like enable it only when the chat has been transferred to live agent?)

We are using the following code to show the file upload prompt.
The same code works for v1 widgets, however, it does nothing on v2 widgets.

I’m using the code mentioned below:

app.sendQuickReplies({
title: ‘Please upload your File.’,
options: [
{ title: ‘Upload’, upload: ‘upload’ }
]
},
{ hideInput: true }
)

Here’s the screen recording for the behaviour on V1 and V2 widgets.
