How to restrict attachments in job application flow

Summary:

Hi Team,

When a candidate is applying for the job, the candidate will submit the attachment one for “Upload picture” (Miscellaneous documents) and another for a resume(Supporting documents), we have a restriction to uploading a resume that is “Add a file not larger than 5 MB” and “Add a file in these file formats: .txt, .rtf, .doc, .docx, .pdf, .html.” but we need to change this error and it should accept 10MB file and it should be in PDF format.

 And for pictures, it should accept only the “jpg” format.

Currently, supporting documents will accept all types of documents except excel and Miscellaneous documents will accept all types of documents, so I need to restrict them.
