What is the name of a toy that keeps turning with two fingers?

Fingertip gyro/thumb gyro

It is a small toy with a central symmetrical structure, which can idle on the fingers. It is a new type of object with a bidirectional or multidirectional symmetrical body as the main body and a bearing embedded in the middle of the main body, which can rotate in a plane. The basic principle of this object is similar to that of a traditional gyro, except that it needs several fingers to grasp and pull it to make it rotate.
