It's simple, you'll get into the Artyou app,
Click on the desired Object
In the lower right corner, there is a Sharing Session
There you will find the owner of that virtual object, the field of Loan, Share a Link and Share Object.
Find the person you want Share with @username or email. If it is not found in Artyou Global, you can share and the person will receive an email to enter Artyou and open what you have sent.
Public Share with link:
For quick things like downloading the photos, Artyou did one share per link. Anyone who has the link will be able to see the Object. Watch out! Just share this with who you really need.
To stop sharing a link, just turn off the share.
