What’s the best way to accept possible reconciliation from someone that hurt you?

I am open to genuine reconciliation or at least a serious conversation with an apology. How do I protect myself from bread-crumbing and being used for attention/validation? To ensure genuine efforts at reconciliation do I continue to block and ignore until this person explicitly asks for reconciliation OR do I respond with secure but detached professionalism to allow them to feel comfortable to ask for reconciliation.

Is it reasonable for me to hold the boundary of “no contact unless you’re serious about reconciliation” and expect them to clearly state their intentions and ignore any messages that aren’t clear and intentional no matter how friendly?

Two of my therapists have told me it’d be good if we eventually made amends and could be civil to exist in our shared friend groups and communities.
