Unity AR Project

Hello, I am trying to build an application for AR placed signs onto buildings using Google Geospatial Creator. I have been trying to do that for the past months, yet I haven’t done much progress. Is there someone that can help me out with this project. I would like to just reach a point of designing and placing Anchors onto the Cesium map. Does anyone have a Sample or anything helpful? I have been trying and the most I have achieved is either a black screen or anchors, based not on geolocation, but related to the phone itself. Any help will be largely appreciated!
