Looking for handdrawn style template

Ladies! Gentlemen!

I want to import simple illustrator drawings into an AE template so that it is shown as a drawing!

A great example of the style I am looking for is this: https://videohive.net/item/whiteboard-explainer-toolkit/18587926?s_rank=25, but it doesn’t allow me to import custom AI/EPS drawings.

If anyone could help me out? Would be greatly appreciated!

Many thanks from the Netherlands,
