How to mirror models in procreate when exported from nomad

I am new to 3D art and am learning Nomad. I can mirror in nomad but when I export to procreate, even though the mirrored models are named shared, they don’t actually mirror each other when painting on them. Can someone advise me how to do this in nomad for export.

Unfortunately there is no mirror in Procreate. The only way to do mirrored painting is to mirror the UVs in Nomad

Thankyou
