I am trying to determine if the pop up message pictured below is legit and what to do about it. It comes up on my Win10 pc but I am not familiar with sideloading or any config settings to enable it.
I did several searches on the LastPass help page and here but I haven't found any reference to it.

In case the pic doesn't load for you the pop up has the title "LastPass Updater" in the upper left and the error message reads "We detected that Sideload may not be enabled on your machine. To ensure LastPass UWP application update is working correctly, please enable sideloading. For further information contact your system administrator."
Thanks in advance for any help or direction!
