AppStore plugins for previous versions?

I guess some apps only support the latest version like 2021 or 2022.

I'm using 2017 version but some necessary apps do not support this version.

Examples are SDLXLIFF COMPARE(https://appstore.rws.com/Plugin/43)  SDLXLIFF TOOLKIT(https://appstore.rws.com/Plugin/77).

I really need two of above but they only support 2021 and 2022 versions.

Please share your info how to install them on 2017 version as well.
