Creating Modpack

[kirsten917]

Hello, I am new to creating modpacks. I have ten mods that I want to use together, and I have successfully uploaded the mods together with the correct versions (1.12.2). When I go to upload the game, it says that I need the following dependencies for four of the ten mods: radixcore 1.12x-2.2.1 or above, llibrary (any), and ichunutil 7.2.0 or above, below 8.0. I have no idea how to add these dependencies to be able to play the modpack, Is this even possible?
