Report Lead follow up activities


I would like to report contact follow up activities, for example, how many phone calls made per day, per week, to who and by which sales. HubSopt report including the report add-on can’t support this. This custom report needs to be shared to none hubspot users. These activities can be easily logged into hubspot under the contact’s timeline, but how can I export to a BI tool to run the report. Through API? then which API and how?

Thank you!
