Align textBox in a Rectangle

Hi,
I’m trying to implement a group template that is consist of Rectangle, will a bell icon floating on top of, overlapping the top rectangular border.
The rectangle should consist a variable length text Block with hebrew letters aligned to right.
I use a “Spot” group type in order the picture to overlap the rectangle but the text block is not aligned to right.
This is the following template i use :


which produces the following results :
image

Only if i change the group template to “Auto”, the text block goes to the right place, BUT, the bell does not overlap the rectangle :

In general i need the text block to be aligned to the right and the bell to overlap the rectangle.
How it can be done ?

On the TextBlock, set { alignment: go.Spot.Right, alignmentFocus: go.Spot.Right }.

Got it,
Thanks
