Edgedriver 88.0.685.3 can't run Edge-dev browser 88.0.685.3 on Linux(Ubuntu)

Question

There is impossible to run current latest Edge browser with related edgedriver (both versions are 88.0.685.3)

Python code:

from msedge.selenium_tools import Edge, EdgeOptions

options = EdgeOptions()
options.binary_location = '/opt/microsoft/msedge-dev/microsoft-edge-dev'
options.use_chromium = True
browser = Edge(options=options, executable_path='/home/vovyc/edge_linux_64bit_88_0_685_3')
browser.get('https://microsoft.com')

Exception raises:

    browser = Edge(options=options, executable_path='/home/vovyc/edge_linux_64bit_88_0_685_3')

Hi,
I believe i found the solution for this (Ubuntu 18.04).
As the default capabilities are for platfrom:windows, you need to manually set the cap to the Linux platform. i.e:

from msedge.selenium_tools import Edge, EdgeOptions

options = EdgeOptions()
options.binary_location = r'/opt/microsoft/msedge-dev/microsoft-edge-dev'
options.use_chromium = True
options.set_capability("platform", "LINUX")

browser = Edge(options=options, executable_path=r"driver/msedgedriver")
browser.get('https://www.google.com')

Please update if this works for you.

Sincerely,
