Disable banners and popups for shared folders

Hello, I am a new Dropbox Professional customer and I am sharing files with my customers to view or download from the web browser.  When they click the link to the shared folder, which I am sending in email or text messages, depending on whether they are on a mobile device or a computer web browser there are several annoying banners and popups that I want to disable.  Every one of these is annoying at best, and frustrating or confusing at worst for my customers.

Computer web browser:

• Sign in with Google popup (I do not want my customers to have to sign in at all)
• Cookies popup (resigned to the idea that this cannot be avoided, unfortunately, but hopeful)
• Want to do more with it banners (recurring blue banners encouraging customers to log in or sign up, I do not want or need them)
• Download popup to log in or sign up (I just want them to be able to download their files)

Mobile device web browser:

• "Open" banner to open installed app (assume this cant be changed but I would rather not have it, this seems appear on EVERY page once they are into the shared folder)
• Cookies popup (resigned to the idea that this cannot be avoided, unfortunately, but hopeful)
• First page asking to Open in App or Open in Browser (also assume this cant be changed, but I want it to just open in the browser without the question)
• Sign in with Google popup (I do not want my customers to have to sign in at all)
• Browse files faster in the Dropbox app banner (recurring blue banners encouraging customers to log in or sign up, I do not want or need them)

How can I make it so that there is a frictionless experience for my customers, where they click the link and they are taken to the shared folder webpage to view or download their files?  It seems that with a paid account I should be able to disable some if not all of these.  Otherwise, I am having to write instructions for my customers helping them to get past all these things and hope that they do not get frustrated or confused and complain.
