Create a configuration file for prefix

[mosoriob]

Is your feature request related to a problem? Please describe.
Daniel is sad because he cannot modify the prefixes. So, we can use a configuration file to it.

Describe the solution you'd like
The prefixes are on the client-side. So, the code must request to the server the prefixes. On server-side, we can create a route to return the prefixes

Describe alternatives you've considered
