Why recaptcha v2 client is evoked where I did not actively evoke the client?

Hi , teams, I integrated recaptcha v2 client for our web to prevent attacks , and I integrated with react project use react-google-recaptcha plugin-in , when need to evoke this client , I will excute " recaptchaRef.current.execute();" sentence . But we found this client will be evoked when user do other operating ，such as turn paging . How to explain this situation？
