luceos the first one works, the second one doesn't, for the record (Root composer.json requires blomstra/realtime >= 0.2.5-beta.6, found blomstra/realtime[0.2.5-beta.6] but it does not match your minimum-stability.).
Anyway, now I'm on 0.2.5-beta.6 and the admin dashboard confirms that, I cleared the cache, but I still see no WS being created.

It appears that when it worked I was on 0.2.4, not 0.2.5-beta.x 🤔
