Window Handle broke

[rhughsless]

Hello.
I have a 2011 3020 DS Sunseeker. I went to open the window above the vanity, and the handle came off. I am afraid take out the glass to try and reglue the handle on. I don't know how hard it will be to reinstall the glass when I put the handle back on. This is a Hehr window. I am attaching a picture of the window and the handle.

Thank you,

Randy
