The slightly fleshy-succulent looks to it, and venation pattern made me think of Peperomia, such as Peperomia rana verde, but the petioles are too green less red. however insufficient light with in store or traveling can cause it loss some coloration.
Perhaps we can see closer photos showing stem, lower part of the plants, any info of the roots or any under-soil structure and the smells when a leaves cut/pinch
