What does this usage of 適当にしてて mean?

Going from context, she was showing them around and gets called by the
director, so she tells him "I gotta go! Sorry!

However I'm stumbled on this usage of 適当にしてて. From context I guess she's just
telling them.. to chill around?




[適当 is a tricky word](https://japanese.stackexchange.com/a/64629/5010), but
the meaning of 適当 in this 適当にする is "random; whatever; laid-back; without
giving it much thought" rather than "appropriate". 適当にしてて means that the
listener can spend time however they like since there is nothing specific to
do. Since this seems to be a party, it means they can enjoy talking to someone
or having a drink. If I understand correctly, "to chill around" could be a
possible translation, but 適当にする doesn't strongly imply relaxation.
