Sorry for being a low tech guy but when trying to follow websites regarding Integrations it can be hard to understand all the required steps.
I sometimes try to contribute and tweak little things but cannot always explain it such a way the owners understand it.
This is a very generic WTH, which is hard to address because of that. Making things more specific can help. E.g., providing an example of where and what can be improved.
