Hi Taavi,
you can either:
Give users or groups the necessary rights to your tasks:
or
Create infolog types, with which the InfoLog entries then belong to a specific group. This group would then have full rights.
This is how we create tasks for the IT team at my employer. All IT employees see the tasks and can edit them. If the task is ultimately to be done, it is assigned/delegated to one or more employees.
Ultimately, however, it depends on how you organize yourself or how the flow of work should be.
If the two options do not fit, you would have to describe your situation in more detail.
