I will not even advise any organisation to do such because these days funny things happen, as you do not know the intention of the person you are taking to the lab when such a person is not a staff member or is affiliated with your organisation, and not even a government official on official duty. It is better if the person stays at your office than to let them into your lab. Labs are basically for major work, and most discreet activities of the organisation's production capacity and abilities are kept there, and I do not believe any reasonable organisation would just take or allow any individual to enter without any prior notice or not follow procedures before accessing the lab.
This is a crypto wallet password recovery service after all, meaning that at any given time, they potentially have access to the contents of the wallets whose password they may have recovered so it's not very safe to bring outsiders to the lab where the recovery is done since you can never really tell who is who these days, the person allowed into the lab might be there to sabotage there place one way or the other and such an act can be bad for business.
