<button name="toggle_start" type="object" class="oe_stat_button">
    <field name="help_button" widget="boolean_button"
        options='{"terminology": {
                "string_true": "ACTIVE",
                "hover_true": "PAUSE",
                "string_false": "HELP",
                "hover_false": "FINISH"
            }}'/>
</button>

is not working in odoo 13. instead of these terminologies it shows a boolean button.
