How to upload .pdb file to the server?

Hi everyone. I’m new to this project and I’m trying to test integration of Sentry with our native C++ application. I can see that after an unhandled exception in our binary the report is submitted to Sentry, but the symbols are missing when I try to view it from the server.

I tried looking in your CP but I don’t see any place where I can upload .pdb files for the executable? Or do we need to set up our own symbol server for this to work?

PS. I’m doing this on a Windows platform.
