How to create Sigma detection rules/alerts for custom logs (365 Defender) ?

[zenon8000]

Under Sigma rules there are no "Logsource - Product" category available for 365 Defender logs.

These 365 Defender logs are not available under "Logsource - Product -> Windows OR m365" category.

How can I create custom sigma rules using these logs ? I don't know how to define product and service fields in Sigma rule:

--- sigma rule ---
logsource:
product: ???
service: ???
