Progress Bar - how to use

Hi,
Any suggestions on how to use the progress bar?
Right now it seems it only displays 0% if the status is not done, and 100% if the status is done.
I have done a lot of work in the notion.so platform and they have a progress bar column available that is super simple, you can just enter a number and it displays that percentage.
A lot of the Monday.com features seem super complicated to me so perhaps I am not the right user for the product. But other advice I have received here from the community has been helpful, so I am asking again on this one!
