Thank you for your prompt response.

Are you able to please let me know how I can lessen the space between the two button for the mobile.

Also, how can I add our personalisation button in the related products or products tab? I made a custom product page in Layouts. On the backend it does show the buttons (https://prnt.sc/0j5E5tzYLxmZ) but when I view the product page on the front end, the personalisation button doesn’t show (https://prnt.sc/O5_nS_vxpEYF).

Thanks for you help.
