Reports in GLPI

Currently, we use GLPI only to receive tickets from our customers, we have approximately 30 customers of which 10 are entities, the rest are locations that are within the same entity, each month a report is passed to customers, we pay a third party to pull the information from the database and pass it to Power BI, we are looking to save cost and want to try some integration of pluguin or any other free software that we can use, the data and graphs that takes the report is.

Translated with DeepL.com (free version)

Total tickets
Tickets by type (Incident vs. Request)
Tickets by status (Open, Closed, In Process, etc.)
Average resolution time
Means of contact (Direct, WhatsApp, Email, etc.)
Ticket Category (Equipment, Applications, Mail, etc.)
Root cause of the ticket
Hours spent per technician
Distribution of tickets by resolver

Can you recommend any application with which I can do this?

The idea is to generate monthly reports with graphs for each client that includes the information shared above,
