I messed up big time. Battery removal.

So I had battery issues which is why I recently bought a new battery. I got the battery today, I opened the phone without any issues. Now the bad stuff comes. There’s these silicone glue type tapes I have to remove in order to remove the battery. I started to pull on them slowly like every guide I found suggested, both tapes on both sides broke. Then I tried wedging it out CAREFULLY using a screwdriver. Note: I did actually did it very slowly and carefully not to rip anything. Then I saw fire. quickly I took the phone and put it in a tupperware container to a safe place. It didn’t really explode, it was a very small minor fire. Now how the do I remove this battery? I still need the data from the phone
