[RMVX ACE] HOW TO INSTALL FREE DLC?

Good day. Just today discovered that for RPG Maker VX Ace came free dlc - RPG Maker: Community Resource Pack. I wanted to install, but nothing happens. I know that all dlc installed in the program folder, in a folder dlc. I looked in the "Properties - dlc" in the steam, but there's nothing there. In the "Manage Projects" watched. There is also nothing.
What do I do?

If its not something that's from or on steam, don't even worry about that. I'm assuming they're just external resources, and you can add them to your game by downloading the resources and using resource manager to add them. (I hope im understanding your post right).

I talked about this dlc for VXAce. How can I add it in the my dlc list? It absolutely free, I press any button on the page with the dlc, VX Ace starts but dlc not in the list of available dlc.
I restarted Steam. It also did not help.

Liberty, thanks.
