hi @debendudas 

You can create new 'widget' and use bellow server script & client script:

server script :

var gr = new GlideRecord('sys_audit');
gr.addQuery('document_key', current.sys_id);  // For a specific record
gr.orderByDesc('sys_created_on');  // Sort by most recent changes
gr.query();

var changes = [];
while (gr.next()) {
    var change = {
        fieldName: gr.fieldname,
        oldValue: gr.old_value,
        newValue: gr.new_value,
        timestamp: gr.sys_created_on
    };
    changes.push(change);
}

data.fieldChanges = changes;  // Pass the changes to the widget client

client script code:

// Display the field changes in the widget template
data.fieldChanges.forEach(function(change) {
    var changeText = change.fieldName + ' changed from ' + change.oldValue + ' to ' + change.newValue;
    // Append changeText to your HTML or Activity Stream view
});
