Sigma Rules Convertor

Hi guys,

As you know, we can import sigma rules to Siem, but in some cases the content does not fit and does not accept. How can we overcome this situation, is there a tool you use to convert?

For example: https://github.com/SigmaHQ/sigma/blob/master/rules/linux/auditd/lnx_auditd_file_or_folder_permissions.yml

Error in the FortiSIEM:Failed to convert sigma rule to fsiem rule: Failed to converted:
There is no EventID or EventCode in Sigma rule.
