FSTP page in 'Debrief' under service request

 Hello,

Can we validate how to access the FSTP when you click 'Debrief' button under Service Request > Task. Pls find the screenshot attached. 

FSTP Home page (in the screenshot) > This is what i get when i open the FSTP std menu under Field Service Technician portal std responsibility. How to get the same under Debrief button (especially would like to access Receive / Return parts under debrief button).

However the FSTP page opens when i Hit cancel after clicking 'Debrief'. So it is somewhere hidden under the Debrief. Cannot expect to access a page after clicking something like 'Cancel'. Can someone please check & confirm. Goal is to access the Receive / Return parts under debrief button.
