Dear @aueaeao
Its difficult for us to recommend any code when dealing with Third-party plugins and and the plugin and Lay Theme get updated on their seperate paths this can lead to ongoing problems.
However i don't wish to discourage you :)
I can only lead you hopefully in a good direction
Searching through what other people on the forum have tried may give you so new options

Apologies that i am unable to help further and Thank you for using Lay Theme
Best wishes and good luck! :)
Sincerely
Richard
