Questions about HyperX SoloCast

My colleague and I are both playing next to each other. The distance between the microphones is approx. 80-90 cm. Unfortunately, we can hear each other twice in the Discord. Is this microphone somehow equipped so that we can no longer hear each other twice? If not, please give us a recommendation. Thank you very much.

does it need a windscreen and if so which one is it?

Is the microphone compatible with the Fifine CS1 microphone arm? and does it have software?

Is there a way to connect the HyperX SoloCast (with USB connection) to a 3.5mm (e.g. external sound card Creative Sound BlasterX G6)? I can't find an adapter, I'm not sure if this is technically possible at all.
