Hii There,

"Like how is this work it is useful to us" is a grammatically incorrect statement.  Most likely, there is a miscommunication or a comment that requires clarification.  Understanding the usefulness or advantage of a specific notion or procedure appears to be the main idea.

I hope this answers your question. You can reach out to ask in case of any other query or to get more information about something. Please feel free to ask, we are here for your help only.

Thanks
