SharePoint Access Requests - Default permissions on accept

Hi

When our users make an access request to a file held within SharePoint Online on any site, the default permission selected when the site owners open the approve page is 'Edit'. The business has requested that the default be changed to 'View' but I can't see any way to do this.

I've tried changing the default group on my test site to 'Visitors' but access requests for files in that site still select 'edit' as the default permission meaning it needs to be manually changed to 'view'.

Is there any method to do what I need or do I go back to the business and state that it cannot be done? Any work arounds anyone can think of?

Thanks!
