How to disable user typing text box with Azure bot

[MeenakshiBalekar]

I am looking for recommendation on disabling attachment and text box when adaptive card is displayed in webchat/directline channel. I am looking for complete code on webchat side.

I tried the sample : https://github.com/microsoft/BotFramework-WebChat/blob/main/samples/05.custom-components/l.disable-adaptive-cards/index.html

However ended up getting javascript error

Can anyone share recommendations on how this can be achieved ? The code behind is composer C#
