They're not getting invaded. Israel temporarily moved ground forces into the 1974 ceasefire DMZ, to make sure no Jihadist attack can be based from there. Syrian gunmen (unclear which faction, but apparently HTS) entered the DMZ, trying to take over several UNDOF positions. the IDF helped the UN troops repel them and returned control back to UNDOF.

(I personally know people who were there, and say this is accurate)
The main Israeli ground effort is digging a major anti-tank/anti-vehicle defensive trench in the DMZ to make future Oct. 7-type incursions more difficult.
Otherwise, the IDF and Israeli navy have been making sure no strategic military assets remain in Syria: From ships, planes & helicopters to air defense batteries (Syria had the densest network in the world of Ground-Air missiles, 70% (109 batteries) have been destroyed) to chemical-warfare plants.
Netanyahu has in the past offered a "peace for the Golan" deal to Syria, latest just before the civil war broke out in 2011.

There's also a report (with conflicting testimonies) that during Netanyahu's first term in 1998-1999, there were secret negotiations via his friend and head of the World Jewish Congress, Ron Lauder, and that Netanyahu was willing to return the Golan for a de-militarization of it and an additional buffer zone.

The existence of the Lauder Memo is well-documented. Whether Netanyahu would have been able to get Knesset support is an open question.
