Compost extract is a different product to compost tea. The main difference is that compost tea is brewed for 12 to 24 hours to multiply up the oxygen-loving bacteria such as bacillus subtillis, which has done a great job for me for years. The difference with a compost extract is that you get a whole range of bacteria from the compost along with fungal spores if it is a fungal compost. Some bacteria are more anaerobic and do not brew up in an aerobic situation, as is the same for some aerobic bacteria; they only multiply once in the soil when connected to the plant, with a need to reproduce themselves to supply the plant with what it nutritionally requires, to get food (rhizophagy cycle).
