Showing search icon on mobile menu + Plus

Hello!
I’m having a problem with the search loupe I would like to put it on the side of the menu, when the menu is on small screens, however it is inside the menu, I tried some solutions by editing the file. mobile.icon.php, however I was only able to insert the icon, but I was unable to open the standard search form. I saw a similar topic where the user @denisgomesfranco managed to solve, but the code that was passed to him did not work for me.

I thank you in advance for your help and I am available.
