Creating subfolders when a new Drive Folder is detected

Hi everyone!
Is there any way to create subfolders whe a new folder is detected
I’m working on automating new clients process an some advice would be grateful
Till now I have a webhook and when a new row in Google Sheets is addes with client information creates a new folder fot this one.
It’d be good to automate the creation of some new subfolders (New client/subfolder 1 - New client/sunfolder2)

Thanks in advance

Yes, it is possible to create sub folder but the scenario you have here is wrong.
