SSRS Report Server View Hidden Shared Data Source Folder

I would like to know if I could view the data source or connection string for those reports. Specifically, I am looking for information such as which databases and tables these reports are generated from, or the connection string itself.

I can go to Report Manager and navigate to the report I want, then go to the Manage section. However, all I see is this:

Is there another place where I can view or amend this data source/connection string?

Could someone advise me on this, please?

Thanks
