Try it? not familiar with loomly but I'd code up the zapier section so that we don't put the nsec in, to solve the last mile issue frostr isn't mature enough yet, other projects to handle multi key management were good ideas but ......sort of abandoned or not maintained, e.g. keycast

also worth checking out self hosting n8n .... worst case scenario i cobble together a nostr native version of this somehow together, self hosted yes we also have the same issue as soapbox does
