MS Teams node SDK: Using express instead of restify in node.js sample?

[NKM122205]

Hi,

    Has anybody been able to use the express web server instead of restify that is used in the "Getting Started" node.js sample for MS Teams? Currently I am trying to use using MS Teams node SDK in an existing app that already uses express and so it is practically not easy to switch to restify. 

Thanks in advance and regards
