NOTE: I have no way to verify if the app in this PR is the one that should be there since apps don't show they version. I'll assume this is the correct one
EDIT: Here it is, was able to find the app key

Safe: https://pr1813--safereact.review.gnosisdev.com/rinkeby/app/#/safes/0x9913B9180C20C6b0F21B6480c84422F6ebc4B808/transactions
I just made sure that deposit and withdraw of tokens from the app works fine. Tried with the DAI token, the only available for rinkeby tests.
