Can't explore folders & files while trying to share on WhatsApp.

Hi,
I'm trying to share files that on my Redmi Note 5 to groups on WhatsApp, but it does not show all the folders on my phone, I can only choose from last files that is obviously not all. But if I want to share photo it can see all folders exist but not the files of course.

• • I know I can go to folders directly, choose a file and then share it on WhatsApp but the problem is that I want to share it on Broadcast group and It doesn't show up with this method.

I shared a video of mine in YouTube so it will be maybe easier to understand what I mean

Do you have a solution for this method?
