Can't see load model button in meshroom 3d viewer

Hi
I know there is another topic on this problem, but it’s closed and seems to be ok for those who have ask these question.
For me it’s not ok…
I’ve tried to double-click on the nodes but there is no reaction. So I can’t export the model.
Could you help me ?
The version is 2020.1.1
Thanks a lot

If you’re asking how to use the piece of software that you found in a repository on GitHub, possibly https://github.com/alicevision/meshroom, the best way to contact the maintainers of that software is to:

  1. Check the README for instructions on how to operate the software, pointers to documentation or troubleshooting info.
  2. Check the SUPPORT file, if one exists for instructions on how to best contact the maintainers for support.
  3. Check the CONTRIBUTING guide, if one exists. Sometimes if there isn’t a SUPPORT file, the CONTRIBUTING guide will give instructions on how to contact the maintainers for support.

All of these documents can be found, if they exist, in the repository where you found the software itself.
