Hope you are safe during this Pandemic.
Try refreshing the relationship tabs using below on form populate code
var iFramesCollection = aras.getMostTopWindowWithAras(window).frames.relationships.iframesCollection;
for (var tabId in iFramesCollection)
I am good , Hope you are safe as well
I tried the above , However while the Form Populates there is no such tab available in the UI, As per my understanding the tab is added only after the CUI changes are implemented.
I tried the Refresh button on the form as well but with no luck.
