Implementing Click Event on Map Visual in Power BI

Hi , VeeraPowerBIDev 

Based on my test and understanding on your requirement, currently we have the option to add "URL" or "hyperlink" as the format to be clicked on but it's limited for using in the matrix and table visuals, so if you want to directly achieve this in the Power BI map visuals, I may suggest you to use a "Cross page drill through" feature to first make the button click redirect you to a table/matrix visual which contains the "URL" to the corresponding file:

You can follow these official links to set up the click-on drill through in your Power BI desktop:

Set up drillthrough in Power BI reports - Power BI | Microsoft Learn

Create a drillthrough button in Power BI - Power BI | Microsoft Learn

You can follow these official links to set up and add the URL link to files in your Power BI desktop table/matrix visuals:

Add hyperlinks (URLs) to a table or matrix - Power BI | Microsoft Learn

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI! 

Best Regards,

Aniya Zhang
