Gap in between phone screen I need help with choosing between 2 risky

I recently decided to fix my own phone screen and it worked for the most part. The only problem was that I had no glue that I could use for the screen so I used 1.2mm double sided tape. The only problem is now there's a 1.2mm gap

Now I have 2 options. Attempt to seal the gap in between the gap with some type of silicon sealant for water tightness Or the hard but cleaner way which is attempting to remove the double sided tape from under my phone screen and doing it the proper way with the right glues.

The tape is applied under the center of the screen and the sides and is quite stuck in place. The tape is "industrial" grade but I'm sure it could come off with heat but I'm not sure if my display could take that heat
