There are three ways you can work with a project you created in Studio Editor (you can find more information here)
So if you want to test your project then you have to download the Wikitude App (log in using your Studio credentials and test the project using the Preview option) or export it and integrate it with your own app.
I want use your tool for an AR app mobile with react native.
In the Wikitude Studio i have this project for test => https://targetmanager.wikitude.com/projects/5ad763050e815048604e5b33
What is the architectWorldURL that i must set in my app for test this project?
Can i test my project only in yuor mobile app?
