home button reassembly questions

Hi all , im having a bit of trouble with getting the home button assembly back on a new screen of this ipad mini 4 i have here .

I fitted a new gasket with the home button ok but the bracket i cant seem to align it so the home button clicks , the home button does still click out of the frame , but im not sure if it's because the tape i stuck the bracket back on with is not strong enough as it does flex a bit .

Also the plastic spacer ring , i assume this fits between the home button and the bracket but does it sit on top of the flex or under it ?

I have some of this tape https://www.amazon.co.uk/gp/product/B00B...

on the way ,hopefully it will be stronger than what i have here , i was thinking of also adding a few drops of hot melt glue for extra support , is that a good idea ? .

any advice appreciated ,
