Hide Toolbar Button from Standard Fiori App F0673A

[yassine_bouchama]

Hello,

i have a requirement to hide this Button "Set to Defer" from Smart table Toolbar.

First i tried to do it using "Adapt UIi" tools, but i couldn't select my button with it.

Second i tried a controller extension with the quick code below to hide the button. I changed value from the model binding the visibility of the button (below).

also tried used ById.setVisible(false) but without success. 

On SAPUI5 Visual Editor all the properties of the button are disable and can't be modified.

any suggestion ? 

Thank you
