Hi,
On the page of your URL if you scroll down the page, you can see the changelog of the plugin. You can see there that the latest version of the plugin was published less than 2 weeks ago.
So yes, it is still active and working.
You can see the whole list of supported payment methods here:
docs.direct.worldline-solutions.com/en/p...ethods-and-features/
Alipay+, UPI - UnionPay International, and WeChat Pay are all listed there so they will work provided that your worldline merchant account is properly setup to accept them.
