How to optionally download and install VS redistributable in Inno Setup

Question

How to create checkboxes at task page to download and install Microsoft Visual C++ Redistributable from URLs?

For example these:

• Visual C++ 2013 Redistributable: https://aka.ms/highdpimfc2013x64enu
• Visual C++ 2010 Redistributable:
  https://download.microsoft.com/download/1/6/5/165255E7-1014-4D0A-B094-B6A430A6BFFC/vcredist_x64.exe

I saw this but I want to download it from URL and install it without adding setup to main program installer: How to create checkboxes at Inno Setup finished page?

I also want to delete the setups from these programs (Visual C++ Redistributable) if they are downloaded.
