How can I save user inputs for gift messages and special instructions in Ella theme?

[anupangadi]

 I am using Ella Theme 6.5.2 by Halo Themes and I have been trying to implement Order Special Instructions and Gift message in both the Quick Cart and the Main Cart. But the Order Special Instructions and Gift message are not getting linked or saved from Quick Cart to Main Cart. And they are not visible in my Test Orders. I need the Order Special Instructions  and Gift Message to be saved on Input from user .Please can anyone help me with this, I would really appreciate any help. Thanks in advance.

                        {% render 'icon-cart-discount' %}
                        <label for="coupon-code">&nbsp {{ settings.coupon_title }}</label> 
                        <input autocomplete="off" type="text" name="discount" id="coupon-code" class="field__input" /> {{ cart.discount_applications }}
