How to claimed rewards from staked ADA

I staked some ADA to a pool using Yoroi and I tried claiming the rewards. Initially I couldn’t figure out where the rewards went. However I found that under ‘Receive’ then ‘Reward’ section, there is a reward address. But how (and where) do I swap it for stable coin? The multiple addresses on Cardano is kinda confusing if you are used to Metamask.
