I have a simple app that displays a sharepoint list in a table. I have a column in the list with the name "Title". I want to display the table filtered on if the title contains the word "Approved" or "Waiting".

Filter('Online GIS User Account Request List', !IsMatch(Title, "approved", MatchOptions.Contains))
Works when it's one condition.

Filter('Online GIS User Account Request List', !IsMatch(Title, "approved", MatchOptions.Contains) or !IsMatch(Title, "waiting", MatchOptions.Contains))
Does not work when I add the second condition with or
