How to add browser inside web app using iframe or other method

We need to be able to embed a searchable browser feature inside of our web app.

We’ve tried using iframe. We must be able to reliably search and save URL results. Currently we can only do it once then it doesn’t work.

Basic process/function of our web app:
Login to our web app.
Select a folder on left.
Search in the embedded browser to the right.
Save URL of selected results.
Return to folder later to see saved results.

In our current version we must copy and paste a URL or use browser extension to save web search results which is not optimal

Currently having trouble because Google blocks because of potential security issues.

See here for some different background and attempts by others.
