I'd investigate multiple desktops - then you could just switch to the desktop containing both your apps.
From Microsoft Support - Multiple desktops in Windows 10
Multiple desktops are great for keeping unrelated, ongoing projects organized, or for quickly switching desktops before a meeting. To create multiple desktops:
On the taskbar, select Task view > New desktop .
Open the apps you want to use on that desktop.
To switch between desktops, select Task view again.
You can then switch between desktops using CtrlWin← and CtrlWin→.
Virtual Desktops in many forms are a great way of dividing up your workflow. I've been using them since the late 90s on Mac [as a 3rd party add-on at that time] & couldn't live without them. It was eventually bought from that developer & added to OS X in 2007. Windows has had it natively since Win10 . It was first used on the Amiga in 1987 and unix X Windows, in 1989.
