Are there ORMs for android that support many-to-many relationships? (programming.dev)

I have no experience with android apps and just started working on one that needs to work with relational data. The relational data has multiple many-to-many relationships and the inbuilt ORM (Room) is leads to class explosion.

While looking at ORM libraries for android, there seem to be many that are out of date:

From 5 of the Best Android ORMs (2014) and AlexeyZatsepin/Android-ORM-benchmark (2017)

ORMLite: 3 years old and the M2M example makes me feel quite queasy
SugarORM: description explicitly only mentions 1:1, 1:n
GreenDAO is unmaintained but replaced by ObjectBox which I haven't yet looked at
Active Android: abandoned
Realm redirects to MongoDB 💀
Freezer: abandoned
DBFlow: no documentation and 3 seemingly abandoned
Requery: 4 years old (abandoned?). Actually my favorite in terms of API
Sprinkles: 10 years old, dead

I'm leaning towards Requery because I like its API the most (hides SQL the most), but haven't looked at ObjectBox yet.

Thanks. It does look like the right library to use. A little surprising that it seems to be the only one that's up to date, but at least it exists!
