How do I get complete list of Variable Collections and Aliases?

Hi everyone,
How do I get a complete list of Variable collections and Alises used in the variables?
So far I have managed to get the collection names, but unable to figure out what to do next?

This is my code so far:
I get the collections like this:

 await figma.variables.getLocalVariableCollectionsAsync();

After that I iterate through the list:

for(let C=0; C<V.length; C++){
 //console.log(V[C].variableIds);
 for(let i=0; i<V[C].variableIds.length; i++){
  console.log(V[C].variableIds[i].valueOf());
 }

This is that the structure of my collections looks like (just a sample text variables)
