[Python] Update a Google docs on Google Drive by api

I'm trying to create a Google Docs on Google drive, with some text inside the Docs. I'm already creating the Docs via api, but i only can update a blank archive.

Does anyone know how to update the text inside the doc and/or add the information when the docs is created?

This piece of code creates the blank docs in python:

doc_metadata = {
'name': 'docs_name',
'parents': [f'{folder_id}'],
'mimeType': 'application/vnd.google-apps.document'
}

try:
doc = drive_service.files().create(body=doc_metadata).execute()
documentId = doc.get("id")
except HttpError as error:
print(f'An error occurred: {error}')
