Google-apps-script – Is google app script able to move a specific folder to the other one on google drive on time or condition triggering

I refer a article to do what I want to move a specific folder to the other one. (The reference article is on the bottom.)

Is it possible to move just the content only?

I made it. But, it also moves the parent folder to the target folder.

It seems to have a command line tool. (I post the reference on the bottom.) Is it able to make it?

function moveFolderToFolder() {
  var targetFolder = DriveApp.getFolderById("theencryptedtargetid");
  var sourceFolder = DriveApp.getFolderById("theencryptedsourceid");
  var currentFolders = sourceFolder.getParents();
  while (currentFolders.hasNext()) {
    var currentFolder = currentFolders.next();
    currentFolder.removeFolder(sourceFolder);
  }
  targetFolder.addFolder(sourceFolder);
};

About the command line tool:

Move large folder from personal Google Drive to a Team Drive

EDIT:
I make a hierarchical graph.
—————————————————
(Before)
——My Google Drive Root
    —sourcefolder
    —targetfolder
(After)
——My Google Drive Root
    —targetfolder
    —sourcefolder

The entire “sourcefolder” had been moved to “targetfolder”.

However, I just want its content to be moved to “targetfolder”.

The content of “sourcefolder” is as below.

——sourcefolder
         —folderone
         —foldertwo
         —file1.txt
         —file2.txt

What I want that as below.

(Expected)
——My Google Drive Root
    —targetfolder
         —folderone
         —foldertwo
         —file1.txt
         —file2.txt

EDIT:
Make a notification for further clearly explaining.
The source folder itself is not to be moved to target folder. Only the content of source folder-“folderone”, “foldertwo”, “file1.txt” and “file2.txe” as the graph showing are to be moved to target folder.
