My scenario :
I am need to send files from one library(native) in SharePoint to a library found in a SPFX webpart. Step two,once the file in the library(spfx webpart) there is a button associated with each files that just send the file using an api to be treated.
I want to know how can this be achieved. Note this scenario is not the definite one,if you guys has a better idea,its welcome.
