Can someone have solutions for this:
I exported data from Power BI Service via 'Analyze in Excel' feature.

When open downloaded Excel file, i have a pivot table can be refreshed. But the issue i have met which whenever i do refresh the pivot, a Login (like image) pop up, then i have to click on the account to process next. And i have tried many way to config connection string for not login when refresh connection, but it doesn't work.

Original connection string (changed private value to xxxx)
Provider=MSOLAP.8;Integrated Security=ClaimsToken;Persist Security Info=True;Initial Catalog=sobe_wowvirtualserver-4e0a2dc1-a733-4709-aeec-xxxxxxxx;Data Source=pbiazure://api.powerbi.com;MDX Compatibility=1;Safety Options=2;MDX Missing Member Mode=Error;Identity Provider=https://login.microsoftonline.com/common, https://analysis.windows.net/powerbi/api, 929d0ec0-7a41-4b1e-bc7c-xxxxxxx;Update Isolation Level=2
