The gimp_gmic_qt version is not going to work with the flatpak. The flatpak is 'sandboxed' and does not 'see' the regular linux libraries. There is no QT support, not looking like there will be in the near future.
The flatpak library files are held in the runtime org.gnome.Platform
It is possible to get BIMP working quite easily, just needs libpcre.so.3 adding to the files
It is possible to get a gmic_gimp_gtk working, version 2.2.4 looks old considering the latest is 2.4.0 but still only from 6 months ago. However it does need many more lib files to get it working.
All (most) of the files you need are here https://my.pcloud.com/publink/show?code=...CxYQKHuNEk There might be more since you use Mint. Run Gimp in a terminal and check for warnings.
Usual guarantee - there is none.

a screenshot there that might help except plugins go in your plug-ins folder wherever that is.
