How to get the missing custom nodes back – Revit

Hi,
Can anyone help me to identify the custom node which is missing is part of which package?

Thanks and Regards,
Rajendra

Hello @rajendra.ganesh that node looks like Archilab_Bumbleebee i guess, try install bumblebbe from package manager

@sovitek You are right it is from Archilab_Bumbleebee. Thank you soo much for helping.
