What is your definition of "detected"? If only direct interaction using the EM field is required, then we have never detected anything...
There are lots of gravitational lensing images of dark matter, we can even see some structures in its shape and distribution.

I really don't get the prevalence of the attitude "If we don't see it with light, it does not exist". Is it that improbable that there is some matter which does not interact with light? imo, similar argument could be made to deny existence of atoms - we cannot see it directly.

Gravitational lensing uses the same mathematics that dark matter is needed to correct.

Read your source. There's lots of criticism in the source itself. If gravitational lensing was proof of dark matter, many someone's would already have a Nobel prize for it. They don't.
