mikro-orm: Modeling relation that doesn't follow naming strategy

My application follow the EntityCaseNamingStrategy and I don’t wish to change that.

There are two tables that I didn’t design and I would like to accommodate.

Basically Account has many AccountSegments. Here is the abridged DDL

CREATE TABLE "Account" (
    "accountNumber" text PRIMARY KEY,
    ...
);

CREATE TABLE "AccountSegment" (
    "segmentId" text PRIMARY KEY,
    "accountNumber" text,
    ...
);

What options do I have to pass to @ManyToOne and @OneToMany to accommodate this? I’ve been trying with no luck along the lines of:

  @ManyToOne(() => Account, { inversedBy: 'segments', })
  account?: IdentifiedReference<Account>;

  ...

  @OneToMany(() => AccountSegment, segment => segment.account, { referenceColumnName: 'accountNumber', })
  segments = new Collection<AccountSegment>(this);
