Since the IP rating is toast once you even break one section of the seal, I just use a thin double sided tape which comes off cleanly like Tesa tape, rather then painful adhesive. Yes, I DID put the awful OEM tape on an S6 Edge+ I sold someone for trade-in as it was a leftover pack (don't ask why I didn't try and repair it; it was BER due to the screen like every other old Samsung with a cracked display and the aftermarket battery I put in was shot, so 2 for 1 situation), but I did that because it didn't matter as I would never see that phone again, so I will be making the life of some recycler hard on a phone which was destined to be sold for scrap.
If it was a long term phone I'd use thin Tesa tape, 4mm or 8mm should be good. Tesa 61395 Tape
HOWEVER, if I was doing a professional repair and it wasn't an old Samsung I am building a cheap hacked together mess from for me to tinker with I would disclose how I do it, and why. Depending on the client I will use original adhesive to give it the best shot at sealing but no guarantees it is fully sealed either. Even my Pixel 6a is no longer sealed as I preferred to make it serviceable.
