Power Query M - Conditional Column based on whether lookup column contains a list of items

I have used the Add Conditional Column process in M / Power Query, but would like to know if there is a way to condense this code to search for items in a list instead of using equals for all of the individual cases.

Example, instead of:

if         "code-code" = "COM" then "DOM"

else if "code-code" = "DOM" then "DOM"

else if "code-code" = "LOC" then "DOM"

something like this

if "code-code" in {"COM","DOM","LOC"} then "DOM"

Nothing that I have tried seems to work and I have searched documentation on MS Docs within Power BI, but have not found anything.

See Notepad of code here:

Thanks.
