Flow - Multi Condition for Metadata

Hello,

I have a problem to make a flow with 3 metadata conditions to validate.

I have a document library with 3 mandatory metadata fields that I want to validate before moving to the next step of the workflow.

What condition do I have to use with the syntaxe : @and(or(not(empty(triggerBody()?['Langue'])),not(empty(triggerBody()?['Niveau'])),not(empty(triggerBody()?['Source']))))

 Thanks
