Power Platform Community Forum Thread Details

we have used modern controls to built the below power apps but its working fine one time and few times its not working. I would appreciate if there are any way to design the below app

As we see below app has stages 1 to 8 when the requestors submit in step 1 then respective department owners who has access to each steps will be able to edit page but then each stage has sequential approval process even though respective department owners has access, however how to achieve this ?
