Return value based on word found in string of text in a cell?

I am building a spreadsheet to help budget some expenses and am trying to automate as much as I can. I have a table in Column H with a keyword like "Gas" or "Electric" and then a corresponding category in Column I that groups this into something like "utilities".

I have a spreadsheet where I export my bank statement and Column B is the vendor and Column C is the amt. I have Column D trying to group all the expenses based on the helper table in Columns H and I to quick and easy organize all the transactions for a month.

I made the formula: =IFERROR(XLOOKUP(B3,ISNUMBER(SEARCH($H$3:$H$35,B2)),I:I),"Uncategorized") to try and get a return and it doesn't work just yet. I feel like I'm close but I'm not as familiar with XLOOKUP as I want and I cant figure out what I could use to make return any easier. Is there a simpler way to get a return like this from a string of text or am I missing something with how the XLOOKUP works?
