Hi, from one noob to another (it is hard for me to tell your level of experience).
If I recall correctly, those keyboards come with an example software that makes them function as a bluetooth keyboard, but I guess you are supposed to write your own code for it.
So if you have just plugged it in via USB to test it and did not uploaded any code from a computer to the keyboard and changed the software it came with, I suggest you try turning it on and search for it in the bluetooth app of you smartphone or computer. If you pair it, you should be able to use it as a bluetooth keyboard and that should be it.
If you uploaded any other code to the keyboard (eg via Arduino IDE or Visual Studio) you need to upload the original firmware, which is included in this repository (here). But if you have no clue how to do that and/or that did not work in the first place, chances are that the original example software is still on it and you can just use it as a bluetooth keyboard as described above.
If you can't upload the original code linked above, or if you need help getting started on how to write your own software for it, I suggest using the Arduino IDE (there are lots of tutorials on many platforms) and if you get stuck, google for the error messages you get and if that doesn't help, ask at an Arduino discussion board, stack overflow, reddit, or such, because the owner of this repository (manufacturer or distributer of the keyboard) will probably not provide much support for getting started. I found that people on those sites are more helpful, if you show some effort of solving the issue, eg. by telling what you tried and describing in detail what did not work as you expected.
Good luck and cheers!
