Gutenberg button block feature

Hello,

The Gutenberg button block is one of the most important blocks of all as it deals with call to actions, but this block is still limited in some ways.
Please can you add display rules to the button block
1. Ability to display button to only logged in users.
2. Ability to display button to only logged out users.
3. Ability to display button to only specific user roles.
4. Ability to display button to only mobile phones or only desktop.

Thanks
