Cannot Share Fabric Data Agent

I created Fabric Data Agent. I published it to M365 Copilot. I shared it to user A, B, C. I copy the link https://m365.cloud.microsoft/chat/?titleId=T_xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx&source=agentCenterDialog. I generated an QR Code using canva. User A, B, C tried to scan the QR Code using their phone, but it returned an error as seen in picture 1. However, when user A, B, C opened it via laptop browser, it was not error. how to solve this problem?
