Hi all,
I'm having trouble managing site permissions in sharepoint because I created a canvas app whose data sources are different lists within the sharepoint site I am talking about.
1. These are the data sources of canvas app

2. The sharepoint site is called "Help Desk" and it contains different lists:

3. I created a group in advance permissions settings in order to allow some users to create a new item, edit and view past items.

My questions are:
- This group has access to all lists included in "Help desk" sharepoint site?
- They are not able to create items in the canvas app, this is the error they are facing. What permission should I give to them if I want them to be able to view, edit, create item but not delete?

Thanks!
Silvia
