Tried to used Junction, but with no luck

@Keep
@Entity(
    tableName = "membership",
    primaryKeys = ["channel", "member", "id"]
)
data class DBMembership(
    override val channel: ChannelId,
    override val member: UserId,
    override val id: String = "${channel}:${member}",
): Membership

And a data class to handle it:

data class DBMemberWithChannels(
    @Embedded val member: DBMember,
    @Relation(
        parentColumn = "id",
        entityColumn = "id",
        associateBy = Junction(DBMembership::class)
    )
    val channels: List<DBChannel>
): Member by member

Both DBMember and DBChannel should be associated by id (primary key).

The code compiles, but returns empty list for channels . Any idea what’s wrong here?
