Lux fund compliance for document storage

One of our institutional investors who holds a SAFEhas their fund based in Luxembourg.  They asked the following when the SAFE was sent to them for acceptance:

"As a fund we are obliged to keep all our transaction documentation in Lux depository. We need to make sure that signing this document in Carta doesn't interfere with our fiduciary responsibilities on keeping the SAFE in the depository.  Is there anyway to clarify that?"

Any advice anyone has on this?
