Include DOI in the 'agsm' biblio style without altering the agsm.bst file?

I would like DOI to appear while using the agsm bibliography style. One solution suggested is to alter the .bst file (see hack for including doi in agsm bibliography style) but working on Overleaf, that is not appropriate.

Another solution would be to use the plainnat bibliography style, but then the first name appears before the last name, and to change that, you need to modify the .bst file too (Displaying author's name in a bibliographic entry in the form: Surname, First Initial of Firstname).

Is there a way to solve this issue without modifying the .bst file? Or is there an easy way to modify it on Overleaf?
