edited after testing: ive reverted back again to much earlier version of chrome to resolve my issue, below is summary from my other discussion:
to summarise (all below using chrome 106, have now also tested 114 which is fine inc click OK)
TC15.53 - recognises the alert/confirm fine including the text within it under a Message property and the OK button
TC15.54/55 - recognises the alert/confirm fine, but only recognises part of the text in it under a NEW child object with ObjectIdentifier "Message" and ObjectType "Label"
seems like an issue with changes in TC .54 to me...
