Uploading PDF file to KOBO form

I am trying to upload PDF file from local computer to show respondents the information from PDF file.
How can I upload PDF when respondent click the link or up-loaded PDF?

Welcome back to the community, @thanzawoo! You could use the file question type to upload a file to the submission when collecting data as outlined in this support article List of Question Types.

No, what I mean is to upload PDF file to show that PDF to the respondent.
