Add lots of generated subscriber data via script

We are generating subscription data for 100 UEs and need to add them via a script.
I assume there is some way to do this via the REST-API or directly push it to the mongo db?
Or do we need to add all the data via the web console? We cant find any docs for the REST-API or a shema for the mongodb.

Hello,

You can refer to this GitHub issue [Docs] How to add subscriber via REST-API · Issue #539 · free5gc/free5gc · GitHub.
