How to get a file picker within the object Inspector ?

Hi, I'm wanting to parse a json file to set data out of code. Yet, I would like to select the json file to use in the unity inspector instead of manually writing its path.

Is there a way I can do so ? I think it might be a type of object in which I could drag and drop my json file from my assets folder. Yet, I don't really know which one I must choose.

PS : Sorry if i'm didn't place this question under the right topic. I'm quite new on the forum.
