How to expand multi lookup SharePoint column in Power BI

[in8awaka]

Hi All,

I am creating a report in Power BI where i have a SharePoint multi lookup column in a list and it is showing me as TABLE and when i am trying to expand the TABLE as we do in single lselect LIST it is not giving me any choice of columns to select 

What i need : i want all the selected values in multi lookup to be displayed as Text seperated by comma. if there is any way to create a custom column with DAX or any other formula

Thanks in advance.
