Unable to back up volume data to Google Cloud storage bucket

Hi, I've been trying for a while now to sync my Google Cloud storage bucket to Runpod so that I can back up my volume data. I followed the instructions provided by the documentation, but I just can't seem to initiate the transfer; it just keeps refreshing, and then I open up the options tab to select whether to upload or download from Google Cloud storage. I created my service account key JSON key. I provide the bucket name and directory path, but it doesn't seem to work. I ensured that the bucket was public, and it is stated on the cloud that it is public. Empty for now, I keep refreshing to see if the data is there, but I see nothing. Any advice on how to get this to work?
