I need help for a project involving wms

I was given a project to complete. I have no knowledge of WMS. I tried searching for some solutions but I couldn’t find it. I need to get WMS URL from the user and overlay it on the globe using a copy-paste box.
I need to make this display in AR in an android app. Can anyone guide me ?

Welcome to the Cesium community!

Do you already have a specific WMS imagery layer you’re testing with? I would first make sure you’re comfortable setting up a CesiumJS project with the getting started guide: https://cesium.com/docs/tutorials/getting-started/

Then check out the WMS code example: https://sandcastle.cesium.com/index.html?src=Web%20Map%20Service%20(WMS).html

We don’t have code examples for AR in CesiumJS but I know some community members have gotten AR projects to work with Cesium. You might need to integrate with an AR library like AFrame, like this project did:
