Custom LinkCommand not working in Modern UI (field displayed as text only)

I have an issue with a link not being displayed on a custom field in Modern UI.

#region UsrInvoiceID 
public abstract class usrInvoiceID : BqlInt.Field<usrInvoiceID> { }

[PXDBInt()]
[PXUIField(DisplayName = "Invoice ID", Enabled = false)]
[PXDefault(PersistingCheck = PXPersistingCheck.Nothing)]
public int? UsrInvoiceID { get; set; }
#endregion

I have also implemented a LinkCommand in the graph, and configured the same LinkCommand in the ASPX page.

In Classic UI, everything works correctly — the field is shown as a clickable link and it opens the expected page.

However, in Modern UI, I do not see a link on the field. It is displayed only as plain text.

I also tried adding a selector control to the field. This makes it appear like a link in Modern UI, but clicking it does not navigate to the expected screen.

Is there a different approach or additional configuration needed for this scenario?
