Please help with white climbing rose ID?

I’m hoping someone can help ID this climbing rose in Zimbabwe. It was purchased as ‘Boule de Neige,’ but I don’t think this ID is correct. It is a strong climbing rose that is appx. 5 metres and doesn’t seem to fit the description of ‘Boule de Neige’ as a shrub.

The flowers are white/creamy white with a moderate to strong fragrance, floral with spicy/clove.

I thought it could perhaps be ‘Wedding Garland’?

Any help would be much appreciated
