To install a modpack on your Minecraft server, open the More menu in your server panel and go to the Modpacks page. There, you can browse available modpacks and install the one you want directly from the panel.
This is the recommended method for Minecraft servers on GameTeam, since the panel is designed to handle the installation automatically. In most cases, you do not need to manually upload server files or configure the modpack yourself.
After the installation is complete, start or restart your server and make sure you are joining with the same modpack on your Minecraft client.
