I have received a shared folder invitation from Thomas Ribar (folder owner: Hyein Lee), but I am unable to access the contents because it requires setting up an authentication app.

When I attempt to proceed with the two-step verification process, I am prompted to scan a QR code and input a 6-digit authentication code. However, I am unsure how to complete this setup and gain access to the shared content.

Could you please provide me with step-by-step guidance on how to properly set up the authentication app and access the folder?

Thank you in advance for your assistance.
