How to set two versions of sketchup as default in pc

How to set two versions of sketchup as default in pc in order to see thumbnails of 3d models from 2017 and 2020 ?

Only one of the versions can be set as the default Open With application for the .skp filetype.

The latest installation should have a thumbsup.dll library that can display both version thumbnails.
If you installed 2017 after 2020, then reinstall the 2020 version and choose the “Repair” option.
