How to insert control groups under 1 custom tab at runtime/during initialization from the separate addins?

[Amadeus111]

In my project, I need to create check boxes dynamically that turn on/off groups (buttons) from separate addins. 

I was able to create check boxes by using Custom Categories 

Components = Categories.GetComponentElements("NRMCustomCategory");
//Then reading the states from other addins 
foreach (ComponentElement component in Components)
{
  string toolState = component.ReadAttribute("tool_state");
  string toolName = component.ReadAttribute("tool_name");
  string checkBoxName = toolName.Replace(" ", "");
//....
}

 Now, my checkboxes turn/on of the groups/controls but in their own tab. I would like to get them together under one tab I created for the main addin. I thought if I can read/write all DAML files during the initialazation I can put them altogether using something like this 

 <updateModule refID="NRM_ArcProMainMenu_Module">
      <groups>
        <updateGroup refID="Group_nrmlinking">
          <insertButton refID="DepButtonCustomCategory"
                        insert="before"/>
        </updateGroup>
      </groups>
    </updateModule>

from my search I found these but I am not sure how to use these or if I am on the right path

My colleague helped me to solve the problem. I was trying work it out from the main addin. Basically, I use 

<updateModule refID="NRM_ArcProMainMenu_Module">
      <groups>
        <updateGroup refID="Group_nrmlinking">
          <insertButton refID="DepButtonCustomCategory"
                        insert="before"/>
        </updateGroup>
      </groups>
    </updateModule>

on the dependent addin which solved the problem
