You can added this code into the ui files so it added export button on your grid.

<exportButton name="export_button">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="selectProvider" xsi:type="string">sales_order_grid.sales_order_grid.sales_order_columns.ids</item>
                </item>
            </argument>
 </exportButton>

NOTE:

you need to replace sales_order_grid with your provider.
