I hope you are well today and thank you for your question.
Do you want to change the logo on hover with sticky logo or light logo version as shown in the attached screenshot?
Or do you want to change the logo to totally different image?
You have to develop custom code to achieve this.
Developing custom code for custom functionality is beyond the scope of support that we provide here. See here https://themeforest.net/item/jevelin-multipurpose-premium-responsive-wordpress-theme/14728833/support
If you are not a developer then you can consider hiring a developer to develop it for you. You can hire a developer from any freelance site. shufflehound recommends the developer https://www.upwork.com/freelancers/~011652ffec8865c6d5
