Google Sheets: Group rows and columns into cells by an ID - google-sheets

Question

I have a table of tasks where rows are grouped using ID's. I want to represent these groupings in another table where there is one row for each ID and all data rows and columns are grouped for each ID in a single cell. I need a formula that can group certain rows into a cell using newlines, and certain columns into cells using delimiters. My data source is something like this:
The formula needs to:
Filter rows by Condition.
Put Task ID's in their own column, one row for each individual ID.
Put all data in Hours, Mins, Customer and Description columns into a cell next to ID so that:
Hours and Mins are joined with a ":" as a delimiter to represent time values
Customer and Description values are then concatenated to time values using space as a delimiter.
The result should look like:
A Google Sheet containing example of the source table and desired result:

SUGGESTION:
You can try this custom formula GROUPDATA using the script below. Just add it as a bound script on your spreadsheet file:
Script:
function GROUPDATA(data) {
var temp = "";
var filtered = [];
var container = [];
var col2 =[];
var final = [];
data.forEach(function(data) {
if(data[0] == true){
filtered.push(data[1])
container.push([data[1],data[2]+":"+data[3]+" "+data[4]+" "+data[5]])
}
});
const unique = (value,index,self) =>
{return self.indexOf(value) ===index;}
var unique_list=filtered.filter(unique);
for(i=0; i<unique_list.length; i++){
container.forEach(function(x) {
if(x[0]== unique_list[i]){
temp = temp+ x[1]+"\n";
}
});
col2.push(temp);
temp = "";
}
for(y=0; y<unique_list.length; y++){
final.push([unique_list[y],col2[y]]);
}
return final;
}
