Is it possible to node 16 in a custom node?

I would like to try to develop a node, but I would like to use an npm package that requires node 16.
In the n8n documentation I read that I have to use node 14.
So can I only use packages that do not require a version higher than 14? Or is there a way?

Sorry, did honestly not try for a while.

You can give it a try and then see what happens or breaks.
