Has anybody tried integrating paytm payment gateway in bagisto e-commerce? Was it successful? Can we use standard PHP sdk and APIs from Paytm in bagisto?

Hello, I am trying to test PWA extension and a part of installation process is to add package "jenssegers/agent" using composer require. However when i execute command "composer require jenssegers/agent" it fails.
How to overcome this or can we use any different package?
