How to add additional buttons to spreadsheet toolbar

Hi,

I am trying to add a custom button to the toolbar of a spreadsheet. Currently, I have the “toolbar” set as “full” in my spreadsheet initialization.
In the custom button implementation it says that we need to use buttons and specify everything from scratch.

Is there a way I can use both, toolbar full and add one extra button custom to my toolbar.

Please let me know how I can approach it.
