How can I do this?
After manually adding easyar.framework (as mentioned bellow), how do I add OpenGLES? (the "plugin" folder no longer exists)
Your instructions (https://help.easyar.com/EasyAR%20Sense%20Unity%20Plugin/Guides/iOS-Project-Configuration.html)
if you are using Unity 2020.2 or later, you need to add OpenGLES Framework manually or replace Assets/Plugins/iOS/easyar.framework with iOS/arm64_fat_static/easyar.framework from EasyAR Sense NR package.
