How to install .sf2 in GB 10.0.2

Hello, some days I'm trying to install and play new instruments in garageband 10.0.2 sf2 format following the suggestions in various posts in the apple support forum. I could use other sounds such as the clarinet solo or solo instruments, however, that in the original library I seem to not find. Once installed in the banks open a new software instrument track, I type info, audio unit DLSMusicDevice, I type charge from the menu and I get the empty folder DLSMusicDevice empty. Then I go out and try banks where there are tools in format .sf2 previously uploaded to try to load it from there. These are visible but gray in character as if he didn't see them. Then I ask, why when I load the tools does not go directly to the banks where they are installed? Maybe missing a step that enables the latter to be moved to the folder DLSMusicDevice? I also know that not all of the sf2 are recognized by GB but I've installed more than 100. I hope you understand something, thank you.

Best regards 😕
