Cant set up Map

Im trying to set up terra swoop force to play with friends but when i load up the world onto the server, the incorporated resource pack and coding it needs to run proplerly doesnt work. i thnk i need to enter a server properties file into the server but i dont know how to do that correctly.

Has someone been able to run the map on Aternos servers?

It says this:

• Download the Terra Swoop Force world from here
• Unzip the downloaded folder
• Copy the server.properties file into your server folder. Note: the server.properties file is configured specifically to ensure the game runs properly. Please be aware that changing options may break the game!
• Navigate to the folder containing your unzipped folder
• Copy the unzipped Terra_Swoop_Force world folder into your server folder
• Start the server
• Players won't have the resource pack automatically, so make sure everyone downloads and activates the resource pack separately. You can get the RP here.

i have no idea how to replace the server properties and insert the resource pack

I dont seem to find a NPC Option in there, maybe its somewhere else?
