What specifications of telephoto lens are needed to photograph the details of an object at a distance of 100m?

First look at the size of the object.

1 For example, if you want to shoot a house 100- 150 meters away, then the focal length of 200-300mm is enough.

If the car is outside 100 meters, it may take 400-500 mm

If it is a small animal or bird, it may not be enough to use 500-600, just add a range finder.

The subject to be photographed is relatively small, and it may be really difficult if it must be 100- 150 meters away.

If possible, you can consider using a telephoto lens of 600-800mm and a rangefinder of 1.4 or twice, but the price is very expensive. Really not, you can look at the catadioptric lens in the second-hand market, and you can buy the required ultra-long focal length at a relatively affordable price.
