What is the license? Is it CC-BY 4 https://creativecommons.org/about/cclicenses/
Yep, this is just CC-BY.
In this case you should add the license into metadata for the asset pack(s):
"Edit asset pack->Metadata->Release Info->License for assets" It will increase the size of audience that will be able to find your art
Already made it. But thank you.
