@Dzung La I believe the logic app URL you are talking about is the Native HTTP Trigger URL that is automatically generated once you save it in your workflow.
Unfortunately, there is no way to find who (which client) has called the HTTP trigger function until and unless your HTTP function have the required body/parameter that specifically calls out from which client the request was initiated.
The possible solution would be your client (in this case azure logic app) passing the Native HTTP Trigger URL along with the logic app name in the request body. According to your logic you can parse these value at your HTTP function app to know which logic app URL and logic app name have called it.
