New to O-S-C & Help Needed with Millumin

Hello All!
I am new to OSC and am looking to use it to see a countdown timer of time remaining on playback from layers in Millumin where OSC receives feedback from Millimun API, I have that documentation but I don't know how to implement it in OSC.
Basically I've never created a new instance in OSC and would like help. I havent yet seen an online tutorial that is helpful, if theres one around please let me know
Any help would be appreciated
Thank you
