How to Share a workdrive folder outside organization ?

Hi, 

Earlier we were using Google Suite and were able to share the google drive folders with external organization ( Auditors , marketing collaterals ) as most of them had a personal gmail account they were able to access it without any issue. How can I provide access to a folder where the external users can upload , edit files in our workdrive ? File types will be Excel / docx .
