Confused about integrating TrustNote with a website project

Hi everyone,
I’m currently exploring TrustNote for a web-based project and I’m a bit stuck. Could someone guide me on the best way to integrate TrustNote into a website(https://vduapkdl.com) (front-end or back-end)? Specifically:

Is there an official JavaScript SDK or API reference for handling transactions directly from the browser?

What’s the recommended way to manage security if the app needs to interact with TrustNote on the client side?

Are there any example projects or tutorials that show TrustNote being implemented in a website environment?

I’d really appreciate any pointers or resources. Thanks in advance!
