At present the ibmplexmonothin font is seen by the mtxrun script

 mtxrun --script fonts --list --all --pattern=ibmplexmonothin*
identifier              familyname    fontname                filename
subfont   instances

ibmplexmonothin         ibmplexmono   ibmplexmonothin
/home/vm/.local/share/fonts/Unknown Vendor/OpenType/IBM Plex
Mono/IBM_Plex_Mono_Thin.otf
ibmplexmonothinitalic   ibmplexmono   ibmplexmonothinitalic
/home/vm/.local/share/fonts/Unknown Vendor/OpenType/IBM Plex
Mono/IBM_Plex_Mono_Thin_Italic.otf

But I don't manage to get the monothin variants loaded.
Any hints available?


Thanks
