Run 3rd Party DLL

Hello

With File/Execute/NXOpen i can choose a dll and start a routine from a siemens drawing frame program. I want to ask if it is possible to run a dll-File via a Journal. I found already a forum topic, where it is recommended to use

NXOpen.Session.Execute.

Following arguments are needed

( [string] libName, [string] className, [string] methodName, Object[] inputArgs )

https://docs.plm.automation.siemens.com/data_services/resources/nx/12/nx...

Is the execute method the right track? We don´t know how to write the syntax, because we don´t know anyhing about this program. Is it even possible to run this file via journal?

Thank you in advance and best regards
