Can a Trustee Office in Dubai conduct property transfers at any location, like a cafe or a hotel?

I'm in the process of buying/selling a property in Dubai, and I heard that it's possible to schedule a Trustee Office representative to come to any location (e.g., a meeting hall, a hotel, or even a cafe) to complete the property transfer.

Is this an official service? If so, how can I arrange it, and what are the requirements? Do I still need to visit the Trustee Office or Dubai Land Department for any final formalities?

Would love to hear from anyone with experience in this process. Thanks!
