Grin ++ getting withdraws from pool

I recently installed Grin ++ V0.5.5 wallet. It is up and running. I cannot find any directions how to use this wallet. .How do I get my Grin sent to me from the pool I am mining at? I tried to send a message through the wallet to tech support and all it does is time out, it wont send.
Thank you,

That’s not really meant for tech support, it’s more for submitting actual software bugs.

It really depends which pool you’re using. Here’s a video tutorial someone uploaded recently. It might answer your questions.
