I want to create a workflow for Change Management list(Items are added by filling the form in it), which will send notifications at the end of the each month and the report can be any file (List, PDF), which also sends email notifications at the end of the month to the Manager.

The requirements of the report are as follows:

E.g, No. of Forms submitted in January 2020
E.g, Per department Forms submitted.

Etc.

Thank you very much.
