Does "Excel.run" Not Work For User Defined Functions?

Is there a way to use Excel.run to fetch data from a workbook and then use that data to calculate a UDF along with the parameters? I know that you can fetch data from the internet and come up with a number (https://docs.microsoft.com/en-us/office/dev/add-ins/tutorials/excel-tutorial-create-custom-functions?tabs=excel-windows Please see header "Create a custom function that requests data from the web") My Excel Example below

/**
 * Bending (Minutes)
 * @customfunction bendingMinutes
 * @param {number} lotRun
 * @param {number} bendLengthInches
 * @param {number} numOfBends 
 * @param {number} easy1OrHard2
 * @returns {number} bendingMinutes
 */
async function bendingMinutes(lotRun, bendLengthInches, numOfBends, easy1OrHard2) {
  try {
    let procEff;
    let secsPerBend;
    await Excel.run(async (context) => {
      const rangeProc = context.workbook.worksheets.getItem("Table").getRange("A2:B7");
      const rangeSecs = context.workbook.worksheets.getItem("Table").getRange("D2:E7");
      procEff = context.workbook.functions.lookup(lotRun, rangeProc);
      secsPerBend = context.workbook.functions.lookup(bendLengthInches, rangeSecs);
      procEff.load('value');
      secsPerBend.load('value');
      await context.sync();
      const response = await fetch(procEff.value);
      const response1 = await fetch(secsPerBend.value);
      console.log(procEff.value);
      console.log(secsPerBend.value);
    });
    if (easy1OrHard2 == 1) {
      return (secsPerBend.value * numOfBends / procEff.value / 60);
    } else {
      return ((secsPerBend.value * numOfBends / procEff.value / 60) * 1.2);
    }
  } catch (errorHandlerFunction) {
  };
}
