Not as it is - you would need to use it as part of a customised proejct that involves editing and extending what is there to suit your client’s needs

Sir, can I do that?

My client asked me to make a like icon to use it on youtube videos. So can I give and give?

** For example: https://elements.envato.com/youtube-subscribes-pack-after-effects-UKT74RL

He asked me to edit and deliver the following content in this link. Can I give this content after I have made the coloring that my client wants and after writing the text he wants?

Note: The main document of the study will never be given to the customer.
