Depending on the bow, I use double backed tape. Easy to put on and take off. Sometimes, I'll slide it under the leather grip very carefully. It could scratch the riser under the leather, but wouldn't be visible there. I've also used contact cement to attach the mounting bracket to leather grips on the outside and cover it with another piece of leather to match the leather grip. Obviously, when I slip the mounting bracket under or glue it to the grip area, it is under thumb area. I've never found that to be a problem. When I use the double backed tape, I run the bracked on the side of the bow, facing down, above the grip area. In all cases, the mounting bracket is mounted vertically, either facing up or down, and the spring arm is positioned 90 degrees to it even with the arrow shelf. Good luck.
