Extracting all icons from a file

Hi all!
Ive been searching for a plugin that can assist me with the following - we have a huge file with our components and screen designs where various icons have been used. However since the project was in different stages, progressed over time, etc. the icons sometimes differ in styling. My goal is to have them all brought in one file and see the mismatching ones to update them and for future have a defined icon library of this project.

A couple of details:

  • all of them are appropriate vector format - fx selection of all vector layers can be another way.
  • all of them are linked to another Icon Library file - fx selection of all layers from X library can be a solution to the case too.
    This would be more manual work.

Do you have an idea what could solve this case? Thank you!
