Telegram on TM

[Vadim]

I decided to contact respected specialists, since I can't solve one task that is quite relevant to me.
I am interested in installing the Telegram application on Terramaster (TM Model F2-421, TOS 5.1.145, BIOS 5.12, SAMSUNG SSD 1 Tb, WD Red NAS Pro 12 Tb). Telegram is required in the version with the ability to export chats. For example, macOS has a Telegram application that does not allow you to export chats, and there is a Telegram Lite application that has a "export chat history" feature.
I need functionality with exporting the chat history.
I know the option of using VirtualBox and Windows installed, but I want to get rid of the constant operation of the virtual machine. At the same time, I do not understand the work of Linux systems well, and accordingly, I cannot install Telegram on TerraMaster via the command line.
Can anyone tell me how to do the installation I need directly on TerraMaster without virtual machines?
Maybe there is an opportunity to do this through Docker, for example?
I will be very grateful to everyone for competent advice.
