Dear @hkim83
There are ways of creating your own arrows to your choosing that can navigate between previous and next projects.
This will require basic knowledge of HTML and CSS

Adding your own "HTML" either in the Footer:

Across the whole website if you wish within "Lay Options" "Custom CSS & HTML"

I have created a very basic setup - i hope this helps you on your journey :)
When you create a Link <a> and give it the class "layprevproject" or "laynextproject" it automatically receives the necessary data to take us to the next-prev project.

So in "Custom HTML & CSS" I have created two simple links with the correct class names

Now what goes within the Link <a> is completely up to you! it could be Text, An image, an arrow etc - ( very basic arrow )

And now i can place arrows in my website - page or footer that operate as links to the next and previous projects.
I hope this answers your question and you have a wonderful day,
Thank you for using Lay Theme
Best
