Need to show a tooltip on Help button using Analysis Service Model Table Data

Hi,

I need to show a tooltip on a button with the language which belongs to the user who has logged in to Power BI.

I just came across a problem working with showing these tooltips with Analysis Service Model Data.

I have added a Help (?) button on a page and tried to add a tooltip for the same from a table in Analysis Service.

I am getting below red rectangle on “What field should we base this on?” dropdown below. There is no error displayed here.

When I select a column from a table in this dropdown, nothing happens.

But, when I try the same thing with test dataset in Power BI itself (static data), it works well and shows tooltip on a Help (?) button.

It looks like it is something to do with Analysis service connected live in Power BI.

Can someone help on this?
