I need help Join/Collecting Rows

So I have an issue with Smartsheet formulas where I am unable to write the formula to join rows. So, if the "left_company" Column values are equal, then join/append the "Timeline Date" values so that the output is showed on the "Timeline" Column. Do not populate the "Timeline" Column if there is already one for the same "left_company" value
