TextFinder was released April of 2019:

function textFinder() {
  const sheet = SpreadsheetApp.getActiveSheet();
  const range = sheet.getDataRange();
  // Creates  a text finder for the range.
  const textFinder = range.createTextFinder('findValue');
  const allOccurrences = textFinder.replaceAllWith('replaceValue');
}
