How to add screen Project Quotes in mobile app of Acumatica

Question

I have tried to add the site map and project quotes screen. but when I publish the project I can't see the screen in the app. Could you tell me what I'm doing wrong?

Thanks in advance.

**Add PM304500**
add screen PM304500 {
 add container "Estimation" {
 add field "InventoryID"
 add field "Description"
 add field "Quantity"
 add field "UOM"
 }    
}

**Update MENU**
update sitemap {
 add item "PM304500" {
 displayName = "Project Quotes"
 icon = "system://Box1"
 }
}
