How to update the main perspective settings？

[zwhaa]

I would like to swap the ego and target vehicle scenarios in the als_cut out. xosc file. The ego vehicle avoids obstacles and the targer vehicle stops when encountering obstacles. The current issue is that I am unable to modify the main perspective of the scene during operation. It keeps following the stopped vehicle, and I want it to automatically change instead of needing to press the "tab" button to switch perspectives.
