How to use rest of spcae of Tails on USB as normal storage like FAT?

Question

I installed Tails on 8GB USB stick with Tails Instructions.

Now I have some extra space on the stick. I searched and found about Encrypted persistent storage.

But I want to use rest of the unused space as normal storage like FAT, NTFS, ex4 etc. That means I can access USB stick from other OS (i.e. Windows, Linux or Mac).

How can I do that?

The Tails website strongly recommends against doing exactly what you're asking:

Plugging your Tails USB stick in a compromised operating system might corrupt your Tails installation, and destroy the protection that Tails provides. Only use your Tails USB stick to start Tails.
