ISM330DLC gyroscope measurement problem

Hello, I am trying to read the measurement results from the gyroscope sensor of ISM330DLC, but the reading values keep returning to the initial value due to some sort of reaction that cancels out the reading values. Below, I present the graph of my measurement results. As you can see, the graph below does not exhibit the characteristics of a gyroscope graph.
Please help me. Thank you
