Hi @Sadiq Hannan
Thank you for posting your question in the Microsoft Q&A forum.
Based on my research, to resolve this issue, you have to ensure you already have the users as Guest users in Microsoft Entra ID by following this article Distribute content to external guest users with Microsoft Entra B2B - Power BI | Microsoft Learn
I really wish I could help you more directly with this, but it's a bit outside my area of expertise. So, I suggest you start a new discussion in the Fabric platform - Microsoft Fabric Community where you'll find dedicated experts who specialize in these topics.
I know how frustrating it can be to get redirected when you're just looking for help, but you're not alone. The Fabric Community is incredibly supportive and full of professionals who are more than willing to guide you through the process and help you find the right solution.
Thank you for your understanding.
