classic 910G GG900 built in 90cm oven and grill?

glass grill door, strip of metal dropped off seems to have been glued to bottom of glass door never noticed this till dropped through bottom of the grill door now it isn't connected seems to get hotter ,have had this a few years never noticed it before can I glue this back and do you know how it fits? and where can I get the glue assume is special glue to resist heat. The strip of metal is about 1" wide and about 14" long, seems to fit to rubber seal blocking heat from oven underneath between doors.
