Changing default camera to *no-support-for-this-app-on-this-forum* and using it from lockscreen

[nicoampl]

I am on xiaomi.eu 8.11.1 and I have installed *no-support-for-this-app-on-this-forum* (*no-support-for-this-app-on-this-forum*).
I prefer this app because in my opinion smoothing is really too much present with stock camera.
I have changed the default camera app in Settings (installed apps then click on the three dots) but when I switch to camera in lockscreen I get the stock camera app instead of *no-support-for-this-app-on-this-forum*.

Is it possible to use the real default camera app everywhere (including lock screen) ?
