Short answer is that you don't have required permissions to share project/deployments. When you share project/deployment, you assign access roles to the selected targets to control how they can use project or deployment. There are three roles available: Owner, User and Observer.
Project sharing
The following table describes the capabilities to share the project allowed by each role.
Deployment sharing
This table describes the capabilities to share the deployment for each role.
* Consumer (roles) can make predictions using the deploy API route but the deployment will not be part of their deployment inventory.
** To Consumer or User roles only.
*** Can remove self only if there is another user with the role of Owner.
