Can I sort cells in Google Sheets with a key function?

I have some data in a Google Sheets document that I would like to sort by computing some value from two columns and using that as the sort key.

Say my data is like this:

I want to sort the data in decending order based on max(C, D) so that the data looks like this:

I was able to do it with a Python script like this, but that required exporting the sheet and then re-importing it.

import csvwith open('source_sheet.csv', newline='') as in_file, open('output.csv', 'w', newline='') as out_file:    reader = csv.DictReader(in_file)    sorted_data = sorted(reader, key=lambda x: max(int(x['C']), int(x['D']), reverse=True)    writer = csv.DictWriter(out_file, fieldnames=reader.fieldnames)    writer.writeheader()    writer.writerows(sorted_data)

Is there some formula or function that can do what I want?
