How to download a mp4 file from an URL in postman by Using bearer token authentication

Hello,
I want to download a .mp4 file by using postman from an url like http://example.com/api/video/example.mp4 however there is an authorization system in this api. I have the token. When I send the valid token by postman, I get a response like “-1”.I don’t want to download the “-1” return. I want to download the original .mp4 file. So I wonder how can do this. Here is an screenshot Can anyone help me please ?. Thank you.
