How can I refuse the tampering of the leader?

Clearly express one's position, inform both sides of the boundaries, etc.

1, clearly express your position: directly tell the leaders that they don't like their behavior and clearly express your refusal. You can take a polite and firm attitude, for example, "I'm sorry, I don't want you to do this."

2. Inform the boundaries between the two parties: When the leader acts, you need to set clear boundaries and inform the other party. For example, "I appreciate your support and concern, but I don't want to participate in any interaction beyond my work scope." Wait a minute.
