How should I remove and replace a newly replaced phone screen?

Hello,

I am trying to replace my Nexus 5x screen. I took apart the phone and successfully removed the cracked screen. Today, I put the adhesive on the phone and put the new phone screen in place, but after pressing the screen into the phone, I realized that I had forgotten to put the earpiece and loudspeaker anti-dust mesh in the new phone screen. Do you have any advice on how I should go about fixing this problem – could I heat up the new screen (will the new adhesive I have put on melt like the original adhesives on the phone) and would I be able to reuse this new screen after removing it and the adhesive stuck to it or would I need to order a new phone screen as well as new adhesive?
