Can I withdraw mined bitcoin from StormGain?

Excuse me, I have a question regarding StormGain and their services. I've been mining some Bitcoin and I'm wondering if it's possible to withdraw the mined bitcoin from my StormGain account. I'm quite new to this and I'm not sure if StormGain allows such transactions. Could you please clarify if I can indeed withdraw my mined bitcoin from StormGain, and if so, what are the steps I need to follow to do so? Thank you very much for your help.
