Hello @Snehal  

You need onChange Catalog Client Script:

function onChange(control, oldValue, newValue, isLoading) {
 if (isLoading || newValue == '') {
   return;
 }
 // Split the input by newlines and count lines
 var linesCount = newValue.split('\n');
 if (linesCount.length > 5) {
   // Trim to first 5 lines
   var trimmedLinesCount = linesCount.slice(0, 5).join('\n');
   g_form.setValue('description_of_the_application', trimmedLinesCount);
   alert('You can only enter up to 5 points.');
 }
}

NOTE: The catch is: user may end up typing let's say 10 lines or points and he/she will not be prompted with anything however the moment click to select any other field to populate value then only the alert will pop-up.

you can use onChange catalog client script for this

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue === '') {
        return;
    }
        g_form.hideFieldMsg('description_of_the_application'); // your variable name
    var lines = newValue.split('\n');
    
    if (lines.length > 5) {
        g_form.showFieldMsg('description_of_the_application', 'You can only add up to 5 points.', 'error');  // your variable name
        g_form.clearValue('description_of_the_application');  // your variable name
    } 
}
