How to calculate  Threshold value in 'WAKE_UP_THS[5:0]' register in LSM6DS3 ?

1 LSB of WAKE_UP_THS = FS_XL / 64

which value it considers for '

WAKE_UP_THS[5:0]' for giving interrupt?. I have just assumed that it may be 'OUTX_L_XL'  and others registers for scanning XYZ wake up.

Please read chapter 5.3 Wake-up interrupt in application note

https://www.st.com/content/ccc/resource/technical/document/application_note/12/98/b4/44/a5/bf/4e/c5/DM00157511.pdf/files/DM00157511.pdf/jcr:content/translations/en.DM00157511.pdf

I have already read that document. But the problem is i am not getting wakeup interrupt according to threshold set. Suppose i want wakeup interrupt at 0.44 g value and set threshold according to that. Now when i read 'OUTX_H_XL & OUTX_L_XL'  i am not getting interrupt even if it crosses threshold value.
