accessing chromium storage fails on debian 11

[houserockr]

If I use the generic load() function, the lib fails in chromium mode:

Traceback (most recent call last):
  File "/home/user/bin/myscript.py", line 247, in <module>
    main()
  File "/home/user/bin/myscript.py", line 236, in main

  File "/home/user/bin/myscript.py", line 187, in test_api
    r = get(baseurl + "/project/" + project)
  File "/home/user/bin/myscript.py", line 99, in get
    s = get_cookie_session()
  File "/home/user/bin/myscript.py", line 81, in get_cookie_session
    cookies = browser_cookie3.load()

Python 3.9.2 (default, Feb 28 2021, 17:03:44) 
[GCC 10.2.1 20210110] on linux

$ cat /etc/debian_version 
11.2

Is it possible, to specify the mechanisms or stores that the load() function should use? If not, that would be a neat feature. For example, I would personally skip the linux dbus libsecret extraction, but keep all the browsers in there. Maybe by specifying a list of callables? load(sources=[firefox,chrome,chromium,opera,edge])

Meanwhile, I'm using the firefox() version, which works so far.
