Protect Directories

Hello,

How do I protect the following directory in case the client removed the Quote Rand Key?

https://demo.invoiceplane.com/index.php/guest/view/quote/q138GXV6OF2aNut

https://demo.invoiceplane.com/index.php/guest/view/quote/

or at least to make it like the below

Respectfully,

Could you please specify what you mean? What quote key should the client remove?

Sorry corrected to the key , in case they removed the q138GXV6OF2aNut

Thanks for the report, added a ticket.
