Darktable HDRmerge alignment

Hello,
Does LUA script for HDRmerge align images before merging?
Use-case: Merging bracketed shots, that are bit off due to strong wind swinging the tripod.
I am using LUA addon for HDRmerge in Darktable and have a feeling the shots were not aligned before merging. There is also no way to check. Just basic HDR controls.

I know there is alignment option in HDRmerge, but I don’t know how to activate it in LUA addon. Maybe someone could share a tip on how it can be done.

From the hdrmerge CLI docs:

The MTB alignment and crop algorithms are enabled by default, and can be disabled with the switches --no-align and --no-crop, respectively.

I don’t see anything in the lua code which turns off alignment.

Stupid question. I have installed HDRmerge and started the lua script. I instructed the module where the executable file was and now the HDRMerge module looks like this. I select a couple of images to be merged and click on the merge button. A couple of brief screens popup and disappear and no DNG is created. What an I doing wrong?

EDIT: It seems the problem is that I have CR3 files and I presume they are not they supported.
