How to Seamlessly Integrate Surveys into Unity?

Hello again!

For an online study where participants answer questionnaires, then play a 2D platformer game and lastly answer questionnaires again, I’m seeking a seamless integration method. My initial idea was to utilize LimeSurvey, which is standard for my university. However, I’m struggling to see how I can implement this without interrupting the flow with a message like “please follow this link now.”

Any suggestions on how I can smoothly integrate LimeSurvey or any other platform into this process within Unity would be greatly appreciated.
Thank you!
