Replacing the glass only on a Tab S6 Lite

My husband is looking to repair the glass screen on my Samsung Galaxy Tab S6 Lite. Touches and the pen still work, so we're assuming we don't have to replace the LCD? My main concern is ensuring the pen will still work after the repair is complete. As IFixIt does not sell it, we purchased a glass only screen replacement from a third party. He already owns the Pro Tech Toolkit and we just ordered an iOpener Kit and glue. I wasn't sure what glue to get, since so many videos simply state “adhesive” without actually saying what kind, so we ordered this… https://www.amazon.com/dp/B09B63HS12/ref...

So here are my questions.

1. Since this will be his first screen repair, any tips? He is watching as many videos on YouTube as possible right now, but the tutorials for my specific tablet are far and few between with no English subtitles.
2. Is the glue we purchased going to work? I'm seriously struggling trying to research what adhesive to use. I am very concerned about the S pen functions still working after the repair, as previously mentioned.
