Hello,
I'm fairly new to Flow and am trying to update a document name.
i created a document library where i have a custom template. (excel file), when i open my template the name is Book1.xlsx by default. i don't want my users to change the name manually.I'd like the file name to be "XYZ-DateTime" but cannot figure out how to do it with the options available in flow.
I tried several things but nothing works. the latest one is

Does anyone have an idea how to do this ?
Thanks a lot for your help !
