pull --rebase origin main (that will get rid of the form_autofiull test failures in CI check)
Remove the test inline use of with driver.context(driver.CONTEXT_CHROME):
commit and push and you should be good to go.
Nice work on the multi-select tabs method, In fact, please rename it to be even clearer.. maybe select_multiple_tabs_by_indices(

[Tracy-Walker]

It's not necessary to use
with driver.context(driver.CONTEXT_CHROME):
All of the methods called already declare it, like in the method you created.

I made the requested changes and rebased but it's still failing the CI smoke tests, not sure why.
