interigating omnisend with shopify subscribation bar

hello this is a easy job i have just canceled klaviyo , because i really dont like their service so i joined up with omnisend for customer service so at the moment i think i still have klaviyo setting on my [login to view URL] in shopify and also in [login to view URL] in snippets ... i might have to delete them... i dont know i asked the customer service that i dont want to delete the subscription bar at the footer and at the top she was helpful and sent me this link [login to view URL] i really cant do this ,,, i know i will mess it up ... so i thought id ask you and pay you for it ,it would be quicker for you,, could you also make the sign up button flash again for top sign up button and bottom sign up button but this time make it flash for 2 second instead of 5 second gap from blue to black.. hopeing for longterm business after this is done.
