Import file (image, video, audio) from the website

I would like to know, can i make the H5P can show the asset from my own website (Similar to Canva/Powtoon, it will be shown in the left or right side of the website), so i can provide the asset from my website, and the user of my website doesn't need to upload the asset by themselves, they just need to find the asset, and then drag and drop it into board?

My website: Wordpress

Thanks.
