Installing a Ring Pro on house with trim

Any ideas on how to install my Ring Pro on our trim? The trim is too narrow and there will be a gap underneath the Ring doorbell.

@Lmiles Hard to say without scale but yes will likely be a gap at the top/bottom where the pro hangs over if it is substantially larger than the existing bell. Ring do make a back plate I think for the pro (its designed to reuse the holes of a battery doorbell) but that will hang over even more. You could get some little blocks of wood to widen the trim in that area although it is aesthetics you are worried about or function?
