@Vasana_Wijewardena add this in client script
onload_post_render(frm){
frm.remove_custom_button(‘Opportunity’, ‘Get Items From’);

},

@Vasana_Wijewardena you can use this script.

onload_post_render: frm => {
setTimeout(() => {
					frm.page.remove_inner_button('Opportunity', 'Get Items From');
			
				
			}, 2000);
}

Thank you

frappe.ui.form.on(‘Sales Invoice’, {
refresh(frm) {
frm.remove_custom_button(“Fetch Timesheet”, ‘Get Items From’);
})
does not work with me
just remove the fetch timesheet button

frappe.ui.form.on(‘Sales Invoice’, {
refresh(frm) {
frm.remove_custom_button(“Fetch Timesheet”);
frm.disable_button(“Get Items From”);
}
})
this is the write code
