External sites - Installing applications via bash (shell)

Guys, good afternoon \ good night \ good morning

I need to install some applications, however, on the network where the NextCloud server is, I can only install them via command prompt. Through the web interface, Admin user does not scroll connection to display the applications and has no way to select to install.

What would be the command to install the “external sites” application?

I’m using NextCloud on:

Operating System: Linux 5.4.0-66-generic x86_64 / Zorin OS 15.3

CPU: Intel (R) Xeon (R) CPU E5-2667 0 @ 2.90GHz (9 colors)
Memory: 6.19 GB

NextCloud’s own information (system):

PHP version 7.4.14
MySQL database version 5.7.33

NextCloud version 20.0.7
SNAP installation
