There is no extension for this gateway.
The payments system is built around Omnipay - https://omnipay.thephpleague.com/gateways/community/ - adding a new gateway that omnipay support is not very hard to do, you just follow the approach of one of the ‘core’ gateways that has the same payment flow.
By the looks of it there is no omnipay support for this provider, so you would be best using the Stripe gateway as a base, and then adding the code you need to make it work around that.
