It will depend on what grounds you’re applying and then what your situation is.
Remote worker for example could be employee for someone else, could mean you own your own business, and they’ll probably want different documents for each.
Need to be specific about your situation, then contact the consular services for various embassies.
Some don’t seem to reply, others do.
The one in Vientiane has been very good at responding to emails regarding the visa requirements.
