MySQL uses the view to report an error, explain/show can not be issued; lacking privileges for underlying table

There is an employee list staff

Add view , Read only 2 A field
CREATE VIEW staff_view AS SELECT name,mobile FROM staff;

Add view permissions
GRANT select, SHOW VIEW ON staff_view TO 'test'@'%' IDENTIFIED BY 'test';

When querying the view , Wrong presentation EXPLAIN/SHOW can not be issued; lacking privileges for underlying table

It's said on the Internet because I didn't give staff Table increase select jurisdiction

But isn't one of the functions of view for security , If staff View permission is added to the table , Then just look up the table directly ？staff_view It didn't play its due role ？
