Is it possible through a function or plugin function to convert a group UUID tex

Unfortunately Content Details by UUID contains only two functions, one for for content objects and other one for models. Nothing for groups.

Some services have explicit APIs to get UUIDs from ids; for example ProcessDesignService.getProcessModelIdByUuid() or ContentService.getIdByUuid().
Unfortunately there's no such method to search for a group based on the UUID in the public API, all methods for this purpose are part of the private API which means it's free to change without going through deprecation, including minor releases/hotfixes. Using the private API might result in your code becoming inoperable after an upgrad
