Copy a specific range to from one sheet to the first empty row and specific column in another sheet

Question

I use Google Sheets and I'm trying to use a script that copies certain ranges from a sheet (that reads CSV files) to a separate sheet's last available row, but to a certain column. I also don't want to copy empty values.

So I need to copy values only of a specific range from a sheet, like Sheet1:A5,D14, where it ignores empty values, to a different sheet's first empty row. but not the same column (so everything moves forward to column CF).

I was able to use this, to copy things to a specific column:

function copyRange(e){
  var copyFromRange = 'Sheet1!B3:J10'; // no row for second cell reference
  var copyToRangeStart = 'Sheet2!B12';
  copyValuesOnly(copyFromRange, copyToRangeStart);
}

function copyValuesOnly(copyFromRange, copyToRangeStart) {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var source = ss.getRange(copyFromRange);
  source.copyTo(ss.getRange(copyToRangeStart), {contentsOnly: true});
}

However, this copies empty rows too, and can't find the first empty row in the other sheet.

I tried using code like this;

function moveValuesOnly() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var source = ss.getRange("B10:AH13");
  var destSheet = ss.getSheetByName("Test");
  destSheet.appendRow(source.getValues()[0]);
}

This only copies a single row, and I can't copy it to a certain column on the other sheet, will always start in "A".

I'm not big on coding, if someone could help me here, that'd be amazing.

In short, the function I need has to;

• copy a selected range of values without formatting
• not copy empty rows
• paste to the first empty available row in a different sheet
• adjust which column it starts pasting the copied data to.

EDIT:

• keep previous data in sheet 2 (new data doesn't overwrite anything)
• function repeatable infinitely, the new data always gets added in the empty rows below in sheet 2.

Thanks to anyone who takes the time to help in advance:)

function copyRange(){
  const ss=SpreadsheetApp.getActive();
  const srcrg = 'Sheet1!B3:J10'; 
  const torg = 'Sheet2!B12';
  const desrg=ss.getRange(torg);
  const row=desrg.getLastRow();
  const col=desrg.getColumn();
  const dessh=desrg.getSheet();
  const src=ss.getRange(srcrg).getValues();
  let cnt=0
  src.forEach((r,i)=>{
    if(r.join("")!="") {
      dessh.getRange(row+1+cnt++,col,1,r.length).setValues([r]);
    }
  });
}
