You can't expect all DMs to be reasonable about creating things that aren't explicit, even when rules for them technically exist, pic related

on two occasion I tried playing a mechanical based trapper, one as an assassin rogue, the other as an alchemist artificer.

The artificer was a kobold acting as a priest of Gaknulak that has several blankets with glued on debris like leaves, sticks, sand, dirt etc. to act as cover and he had the mold earth cantrip as a racial, so I often created pitfalls traps, but the DM was a dick and everyone ignore the traps and moved around them as if they spotted them. I gave up on making traps 3 sessions into that that campaign when a zhentarim on a horse moved over one the space where I had a trap and when I pointed it out the DM says "the horse jumped over it"

sad times.
