This will not help you retroactively for instances that have already run, however, in your Flow, if you use the expression:
concat('https://us.flow.microsoft.com/manage/environments/', workflow()['tags']['environmentName'], '/flows/', workflow()['name'], '/runs/', workflow()['run']['name'])
This will generate the hyperlink to the specific run history item of the currently running instance of your flow. If you had a column in the same SharePoint list that is triggering your Flow named something like
[LastFlowRunHistoryLink], then your Flow could set the value of that field to the above expression as one of its execution actions. At that point, your SharePoint item would always have a hyperlink to the last Flow instance that ran for that item.

Note: If you are using a government tenant, make sure the replace the
us.flow.microsoft.com in the first
concat parameter with the base Flow url for your sovereign government tenant.
