Telegram flew to Linux by itself, how can I log in using the cache?

Question

linux

Hello. I will say right away that I am a complete teapot, well, quite right!
I have Linux on a virtual machine - ORACLE VM VIRTUAL BOX, WHOINIX WORKSTATION
Today I launched a virtual machine, I launch telegrams on it, and I am prompted to register / enter a number so that the code comes to it. This number is no longer there, there is no possibility to restore it either. It turns out that the cart itself got out.
Shouldn't it automatically enter the cache, as it happens on the same Windows? And how to see where in general this cache is stored? I found this topic: Where is the Telegram cache stored in linux ??? but I absolutely did not understand anything in the answer of this person Maxim Moseychuk , I repeat, I am a complete teapot in this Linux.
I will be very grateful if you can help me!!!
