So I've found here which is the procedure for it:
With everything stated above, go the the following site and register your application here.
At the end of the online process, you will get a Statement for Visa Application. With this printed Statement and the hard copies of everything you prepared, you will go to the Consulate. At the Bolivian Consulate in Buenos Aires, we got out with the Visa after 40 minutes.
You can do all the preparation before your departure, so that when you arrive to the Consulate you have all your papers ready.
PS:
This part was written after I got the visa. The hard copies and photos are not needed. I had them but they said they are already saved in my visa application. I got the visa from Bolivian Consulate in Buenos Aires, Argentina. Could be different in other locations.
