Question mark in Zerotrust Acces Application domain

Ì need to redirect a user to an application with this URL in Cloudflare Access:

So I enter: ?token=xxxxxx in the path but Cloudflare removes the question mark and everything after when the user is redirected to the app.

Is there any way to include question marks in the URL. I really need it (I have no control on how the app is working).

Thanks for your help.

Here is where I am having the problem:

Is someone can test it?
