Feature request: GAL support in recent versions

[Giermann]

Your environment

TbSync version: 4.11
EAS-4-TbSync version: 4.12
Thunderbird version: 128.1.1

Issue

EAS-4-TbSync supported address lookup in global address book before TB 102 came out.
Occording to #167 (comment) this should be addressed after the initial release, but still - even after update to support TB 128 - there's no GAL support yet.

It would be great to get GAL lookup back in recent versions of TB / TbSync.
